Impact of Insect Protein Meals on Pet Food Palatability
This article will focus on the incorporation of insect protein meals into pet food and the evaluation of its impact to palatability in dogs and cats' diets by analyzing the last public research available on this topic.
Insect Materials as Pet Food Ingredients
Last decade, the use of insect ingredients as balanced sources of proteins and fats has become a global reality. In each continent, we can find research centers and universities with projects focused on insect materials and their use in humans, livestock and pet food diets.
Big scale production has also improved, so big hurdles to becoming profitable for producers and affordable for customers are about to be overcome. This positions insect meals and oils as relevant sources of proteins and lipids for the pet food industry.²
Insect ingredients not only meet the nutritional requirements for pets but are also a great tool for claiming sustainability, lower carbon footprint and innovative ingredients, just to name a few.³
While insect proteins can have a lower environmental footprint than most animal proteins, this is not as significant for the pet food industry, since pet foods mainly incorporate low environmental impact animal by-products from the rendering industry.⁴
Currently, the main sources of insect oils and meals are black soldier fly, mealworm and cricket. They are considered as good alternative protein sources and mostly have adequate amino acid levels, meeting the standard requirements for dogs and cats.⁵
In insect materials, protein is the nutrient composing the largest fraction, with values ranging from 40% to more than 60 % on a dry matter basis.
Fat makes up the second largest fraction, and generally, insect materials contain lower levels of ash compared to other animal protein sources (see Table 1). Insects are also packed with micronutrients, including iron, zinc, calcium, and B-vitamins, which are vital for various bodily functions.⁶
Table 1. Average nutrient composition of selected form of insects on a dry matter basis.
One key property of insect ingredients is that it is possible to modulate their nutritional composition by changing the feeding during the insect rearing. Several studies confirmed this by investigating the impact of different diets on the content and amino acid profile, lipids and other nutrients in insect protein meals and oils. Consequently, we could find insect meals and oils from the same species but with a different amino acid profile or fatty acid profile.¹² Therefore, insects represent versatile raw materials for the pet food industry with fast growing expectations in the market.
As per Rabobank's research of 2021, see Figure 1, the global volume of insect ingredients incorporated in feed and pet food is expected to grow up to 500K MT by 2030, predicting pet food to be the second largest market.¹³
Figure 1. Increase of the insect production and use in feed and pet food.
According to a review done in 2023, there are 43 insect-based pet food brands active around the globe, 35 of which are operating in Europe. Black soldier fly and mealworm are the most used species in pet foods.¹⁴
Despite the various advantages of using insect ingredients there are other aspects that must be evaluated when applying them in pet food. This includes potential allergic reactions, contamination risks during production, stability and shelf-life concerns and the ability to meet the nutritional needs of cats and dogs in a specific recipe.
Insect Ingredients Effect on Palatability
Another important factor and key to the success of a diet is 'palatability'. Palatability is a critical factor in pet food acceptance. Cats are notoriously picky eaters, and their willingness to consume food is influenced by its taste, aroma, and texture. Therefore, understanding how insect protein affects these sensory attributes is essential.
Insects have unique flavor profiles that can vary significantly between species. For instance, crickets have a nutty taste, while mealworms can be more neutral. These flavors can be both an advantage and a challenge when formulating palatable pet foods.
Edible insects were first promoted as a sustainable method for food waste bioconversion, and it seems this practice is already implemented in Asia. However, how the heterogeneity of food waste sources affect fat oxidation, flavor and palatability of the final insect meal for pets is not well understood.
To maintain or improve palatability, manufacturers use flavor enhancers, fats, and other ingredients to mask or complement the natural taste of insect protein. For example, adding chicken fat or liver flavor can make insect-based pet food more appealing.
Currently there is limited reliable research on palatability of insects in pet foods, but we expect more long-term research to be done in the coming years to allow a standard and better evaluation of this factor. However, we could find in the literature some interesting palatability studies thanks to a review done by Bosch and Swanson.¹⁵
Some studies found that regarding palatability of insects, dogs and cats showed different preferences depending on the insect species and the inclusion rate of the insect ingredients.
In 2018, Beynen reported that dogs showed a preference for dry foods containing black soldier fly larvae meal over those with yellow mealworm meal (intake ratio of 60:40; n=10), whereas cats preferred the yellow mealworm-based food (40:60; n=10). Both insect meals represented 30 % of the total crude protein in these diets.¹⁶
In 2020 Kilburn et al. showed that a banded cricket meal inclusion rate of 8, 16 or 24 % in extruded pet foods did not affect the intake in dogs (n=8).¹⁷
Regarding cats' palatability, Paßlack and Zentek published in 2018 that 3 out of 10 cats had refused a food containing 35 % black soldier fly meal and 3 cats had an intake between 78 and 87 % of the food offered.¹⁸
For a food containing 22 % black soldier fly meal, one cat vomited and then refused the food completely and two cats had lower food intakes (83 and 88%).¹⁷
In cats fed a diet containing 5 or 20 % of black soldier fly meal for 2 days (n=20 per diet), 38 and 54 % of food was consumed. None of the cats rejected the 5% black soldier fly diet, whereas one cat rejected the 20 % black soldier fly meal diet.
Future Prospects of Insect Protein in Pet Nutrition
Insect protein represents a promising frontier in pet nutrition, offering a nutritious alternative to traditional proteins. The impact of insect protein on pet food palatability is a critical factor that manufacturers are actively addressing through research, innovation, and consumer feedback.
While insect protein holds great promise, there are challenges that need to be addressed to ensure its widespread adoption in the pet food industry.

Starting in January, the company will unify its operations in Mexico, Central America, and South America under a single regional structure, with the country assuming a central role as a platform for leadership, innovation, and expansion. This reconfiguration marks a new growth cycle for the company in the region and is accompanied by the creation of 46 new positions across various Latin American countries.
According to Rubens Castro, president of Kemin's Animal Health and Nutrition unit in South America, the decision reflects a clear vision for the company's future.
'The decision stems from a clear vision for Kemin's future. We understand that this configuration expands our competitive capacity, promotes greater strategic alignment, and accelerates the capture of market opportunities.'
Regional integration was guided by three main pillars: greater strategic synergy with a focus on the customer, operational efficiency with faster decision-making, and the construction of a solid platform for sustainable long-term growth.
Brazil as a hub for leadership and innovation
Brazil's leading role in this new configuration goes beyond its economic weight. The country concentrates Kemin's most complete operation in the region, bringing together production plants, innovation centers, experienced technical and commercial teams, as well as a consolidated presence with key clients.
According to Castro, 'this centrality stems not only from the country's economic size, but from a combination of structural, operational, and leadership factors that strengthen the region as a whole.'
He emphasizes that 'Brazil represents the largest economy in Latin America and concentrates a significant portion of our business volume. Its scale, diversity of segments, and Kemin's consolidated presence make the country a natural hub to lead regional initiatives and accelerate integrated growth across all geographies.'
Furthermore, the Brazilian structure functions as a platform to support expansion in Mexico and Central America, promoting the sharing of technology, knowledge, and best practices. "This solid foundation allows the country to serve as a platform to support expansion in Mexico and Central America, sharing technology, knowledge, and best practices," the president emphasizes.
Direct impact on the growth of Business Units
With unified leadership and a more cohesive region, Kemin is now aligning commercial strategies in a more coordinated way, expanding the presence of its Business Units in different Latin American countries.
According to Castro, the new structure creates concrete conditions to accelerate results. 'With a single leader and a more cohesive region, we can align commercial strategies, prioritize markets, and expand the presence of Business Units in the countries in a more coordinated way. This means more opportunities for cross-selling, portfolio expansion, and entry into new segments, supported by a clear and integrated regional vision.'
Integration also brings important operational gains, such as faster product launches, better access to data and market intelligence, and resource optimization. "This scale allows Business Units to focus on what really matters: developing differentiated solutions and growing sustainably," he states.
Ambitious goal: to double in size in three years
With the region now operating in an integrated manner, Kemin expects to grow above the average of the markets in which it operates. Strengthening its commercial presence and expanding its portfolio are cited as pillars of this growth.
Castro emphasizes that the company's focus on Latin America will be even more strategic in the coming years. "Our goal is to double in size within three years. Kemin Industries will have a special focus on the region, with significant investments such as new plants, new laboratories, capacity expansion, and personnel."
46 new positions reinforce regional presence
To support this growth, Kemin announced the opening of 46 new positions in Latin America, with approximately 70% of the vacancies focused on the Commercial area. The opportunities will be distributed across Brazil, Colombia, Argentina, Chile, Ecuador, Mexico, and Central America.
According to Giseli Delacqua, Human Resources Director at Kemin South America, the move represents an essential strategic step for the company's future in the region.
'The opening of 46 new positions by Kemin in Latin America represents a fundamental strategic step to sustain the company's accelerated growth in the region. This move reinforces the company's commitment to expanding its presence in Latin American markets, especially after the integration of operations in Mexico and South America under a single regional structure.'
The increased focus on the Commercial area is directly linked to the strategy of proximity to the market. 'We are directing most of these new positions to the Commercial area to strengthen our market presence, especially in regions where we have little penetration and representation,' explains Giseli.
She adds: 'We will have more resources to be closer to our local clients and partners, and this will help us respond more quickly to market demands, increasing our capacity for innovation.'
People, purpose, and values at the heart of the strategy
In addition to growing its team, Kemin emphasizes that it seeks professionals aligned with its values and purpose.

Understanding the Role of Antioxidants in Pet Food Preservation
What Are Antioxidants and Why They Matter
An antioxidant is a molecule that protects cells from damage caused by free radicals. Antioxidants in pet food prevent fats and oils from breaking down through oxidation. Oxidation can lead to rancidity, off-flavors, reduced aroma, and the loss of essential nutrients, ultimately affecting the pet's willingness to consume the food.
Sara explains:
'Without proper antioxidant protection, even a well-formulated product can lose its nutritional integrity and appeal over time. Antioxidants are not just additives—they're crucial for product performance.'
For more details on how oxidation control in pet food works, see Kemin's Oxidation Control solutions.
The Bigger Picture: Why Antioxidants Impact Palatability
Oxidation doesn't just affect nutrients—it also influences flavor, aroma, and palatability, which are critical to pets' acceptance of food. Sara notes:
'Even minor changes in flavor or smell can lead pets to reject a product. Using antioxidants correctly ensures that the food not only remains nutritious but also appetizing for cats and dogs.'
For more on enhancing flavor and pet acceptance, explore Kemin's Palatability Solutions.
Choosing the Right Antioxidants for Your Product
Not all antioxidants are created equal, and their effectiveness depends on the type of fat used, processing methods, and storage conditions. Sara highlights that selecting the right pet food antioxidants is about understanding these interactions:
Type of fat or oil matters: Some fats oxidize faster than others, requiring different antioxidant strategies.
Processing conditions affect stability: Heat, moisture, and extrusion processes can impact how antioxidants perform.
Storage and packaging are critical: Packages are exposed to a variety of conditions over their lifecycle — from heat and humidity during transport to oxygen exposure once opened by the pet owner. That's why Kemin tests antioxidants under worst-case scenarios to ensure stability and performance.
Kemin offers tailored solutions to match these needs, including PET-OX® synthetic antioxidants for overall stability, TERMOX® ethoxyquin-free antioxidants for sensitive formulations, and NATUROX® natural antioxidants for clean-label products.
Strategies for Effective Antioxidant Use
Sara shares practical tips for incorporating antioxidants in pet food:
Evaluate raw materials carefully: Understand the oxidative potential of fats and oils used in the recipe.
Match antioxidants to processing methods: Choose antioxidants that maintain stability through extrusion, baking, or other manufacturing processes.
Monitor storage and handling: Use proper packaging, limit air exposure, and educate distributors on optimal storage practices.
Test and validate: Regularly monitor oxidation levels and sensory attributes to ensure products meet quality expectations.
By following these strategies, manufacturers can deliver consistent, safe, and palatable products that pets enjoy while maintaining nutritional integrity.
Pet food antioxidants are more than just additives—they are essential tools for maintaining pet food quality, safety, and palatability. By carefully selecting antioxidants, considering processing conditions, and monitoring storage, manufacturers can ensure their products remain fresh, nutritious, and appealing to pets.

Palatability in Wet Pet Food: Key Insights for a Growing Market
One dimension remains crucial to both pets and their owners: palatability. Understanding the factors that influence flavor, aroma, and texture particularly through processing and formulation is key to creating wet pet food products that succeed in a competitive and rapidly evolving market.
Wet Pet Food Takes the Lead: Trends, Insights, and Innovation
In 2024, Wet Cat Food dominated new pet food product launches in the EMEA region, continuing a trend that has held strong since 2020. According to the Innova Database, this segment accounted for 25% to 30% of all new launches over the past five years. While Wet Dog Food trailed slightly, it maintained a steady presence, contributing between 12% and 18% of annual launches in the same timeframe. Combined, wet formats for cats and dogs have represented over 40% of new product development efforts since 2020, a testament to their enduring appeal (figure 1). In this context, understanding the key drivers behind consumer choices becomes essential for developing products with true differentiation.
Figure 1: Innova Database New Pet Food Launches in EMEA 2025 (2)
The wet pet food market's sustained growth is powered by converging trends in premiumization, health-focused formulation, and sustainability. Today's pet owners seek organic, grain-free recipes enhanced with visible functional benefits to support overall health and wellness. Wet food has a high moisture content which helps with hydration and digestion. Convenient packaging is also a big advantage. Formats like single-serve trays and resealable pouches keep food fresh and easy to use. At the same time, eco-consciousness is growing. Brands are now expected to use recyclable materials and source ingredients responsibly. 3
Palatability has long been a cornerstone of product differentiation and premium positioning within the pet food industry. Wet food, in particular, is widely recognized for its superior palatability. However, in the face of intensifying competition, an expanding variety of products, evolving raw materials, and new processing techniques, manufacturers are now exploring ways to further enhance palatability offering added value and reinforcing brand loyalty in an increasingly crowded market.4
Palatability in wet pet food remains a complex and evolving field, with much still to uncover. However, recent research continues to reveal promising strategies to enhance flavor appeal and feeding enjoyment. In this context, two key areas deserve closer attention: the influence of processing techniques on palatability and the strategic use of palatants to elevate sensory experience.
Time, Temperature, and Safety: The Role of F₀ in Wet Food Manufacturing
To truly grasp how wet pet food processing influences palatability, it's essential to start with the parameters that control thermal treatment, primarily time and temperature. These two factors shape what's known in the industry as the F₀ value.
In wet pet food production, F₀ is a key measure used during heat processing (called retorting) to make sure the food is safe. It tells us how efficient the heat treatment is to kill harmful bacteria. F₀ is expressed in minutes and represents, for a certain temperature and time, the equivalent duration of the sterilization at 121.1°C (figure 2). It was determined that to eliminate Clostridium botulinum in 12 logarithmic units (12D), foods must be exposed to a temperature of 121.1 °C (250°F) for 3 minutes. Thus, an F0 value of 3 minutes is generally regarded as the standard in the wet pet food industry, ensuring adequate reduction of most microorganisms to meet safety requirements.5 However, many pet food manufacturers will choose to have higher values such as 5, 25, or even more.
Figure 2: Formula of the retorting value (6)
But safety is just one side of the equation. The F₀ value also plays a critical role in preserving the flavor, texture, and nutrient density of the final product. Typical sterilization processes operate within a temperature range of 120–130°C, with cooking durations ranging from 10 to 120 minutes, depending on the formulation and packaging. Fine-tuning these variables can profoundly impact not only microbial control, but the sensory experience that drives consumer acceptance and animal enjoyment.
Cracking the Code: How Retorting Conditions Impact Palatability in Wet Pet Food
To explore how thermal processing influences palatability in wet pet food, Kemin conducted a targeted study using a turkey and giblet loaf recipe for cats. The formulation included 1% PALIVATE™ WP.65 Dry as a palatant. Seven distinct versions of the loaf product were prepared by varying the retort time, temperature, and resulting F₀ values. Cooking temperatures were set at 110°C, 120°C, and 130°C, while time ranged from 36 to 150 minutes, generating calculated F₀ values between 10 and 140 minutes.
To evaluate palatability, all variants were subjected to a versus test at a third-party cattery in the United States. Each product was tested one versus each other over two days, involving a panel of 30 cats. The statistical significance of the preferences was assessed for each test using a Student t-test, allowing for a rigorous analysis of the impact that processing conditions had on sensory acceptance.
The summarized palatability results of this evaluation are presented in the following table (figure 3).
Figure 3: Palatability Results Across Seven Wet Cat Food Formulations
Among the retorting processes tested, the longest heat treatment (303 minutes) showed a clear decline in flavor appeal, while the shortest process, just 36 minutes, consistently delivered the best results across the board. Shorter retorting times at a constant temperature clearly emerged as a key factor in boosting palatability. Higher temperatures also played a positive role, with the top-performing recipe processed at 130°C for 36 minutes (F₀ ≈ 80), closely followed by 130°C for 41 minutes, which had the highest F₀. Surprisingly, a product processed at the lowest temperature and F₀ value (110°C for 148 minutes) still ranked well against medium F₀ products, suggesting that maximum heat treatment does not always equal maximum palatability.
These findings reaffirm that the retorting process plays a significant role in shaping the palatability of wet pet food. Both processing temperature and duration influence the final sensory quality, with shorter cooking times and higher temperatures generally yielding more palatable results.
Tailoring Taste: Innovations in Palatability for Wet Pet Nutrition
While wet pet food is known for its high palatability, there remains room for improvement. As seen together, one key area is process optimization, particularly the thermal treatment during retorting. Another promising avenue is the use of palatability enhancers. It's important to note that these enhancers differ from those used in dry pet food, both in composition and application.
In dry formulations, palatants are typically sprayed onto the surface of kibbles after processing, delivering immediate flavor impact. In contrast, wet pet food requires palatants to be incorporated directly into the blend prior to the retorting phase. This distinction means that wet food palatants undergo transformation during cooking. Flavor development occurs through in-process reactions such as protein hydrolysis and the Maillard reaction, the latter being particularly influential during retorting. To be effective, wet palatants must include the right precursors to enhance these reactions and generate a desirable aromatic profile by the end of processing.
To evaluate palatant efficacy in wet food, manufacturers often rely on similar testing protocols as for dry food. Typically, preference trials involving 20 or more animals over a two-day period. Beyond flavor, texture is another critical consideration. Producers are now looking at how palatants can be tailored to complement the physical characteristics of wet formulations, ensuring both sensory appeal and technical compatibility.
Palatants in Chunk-in-Gravy Pet Food: Where Placement Makes the Biggest Impact
One frequently asked question in wet pet food development, in chunk-in-gravy formats, is where to incorporate palatants for optimal palatability: in the chunks or in the gravy? While further research and palatability testing are needed across various formulations, palatants, and processing conditions, initial findings have begun to reveal some promising trends.
A series of trials conducted with three different palatants offered early insights. For the first two palatants, 2% was added either into the chunk or into the gravy and compared against a control with no palatant. The first palatant demonstrated a clear improvement in overall palatability versus the control, though no distinction could be made between the two application methods. In contrast, the second palatant yielded better results when added to the gravy, indicating that the carrier matrix can influence palatant effectiveness.8
A more comprehensive study was then performed using a third palatant applied at 1%. Four formulations were tested: one without any palatant (Control 1), one with a 50/50 distribution between chunk and gravy (Control 2), one with palatant entirely in the chunk, and one with palatant entirely in the gravy. Both palatant-enhanced products outperformed Control 1, with the gravy-only application showing statistically stronger results. Compared to Control 2, only the gravy-focused formulation showed a significant increase in consumption, suggesting that incorporating palatants in the gravy may be the most effective strategy (figure 4).
Figure 4: Palatability test with different inclusion in chunk and gravy formula (9)
However, this approach is not without its trade-offs. The inclusion of palatants in the gravy can impact product color, which is an important aesthetic and consumer acceptance factor. To mitigate this risk, a balanced application, splitting the palatant between chunks and gravy, might offer a functional compromise. While the preliminary data points to promising directions, further in-depth studies will be essential to confirm these findings and refine best practices.
Conclusion
As wet pet food continues to capture a significant share of product innovation, the challenge for manufacturers goes beyond meeting basic nutritional and safety standards. The insights gathered from research into thermal processing, F₀ values, and palatant strategies underline the importance of precision in both recipe design and production techniques. Whether enhancing Maillard reactions through controlled heat exposure or determining the optimal placement of palatants within chunk-in-gravy formulations, these refinements are pivotal to delivering elevated sensory experiences that drive pet preference and owner satisfaction. The path forward will require continued experimentation, deeper understanding of ingredient behavior under thermal stress, and a willingness to rethink conventional approaches, all in pursuit of the perfectly palatable bite.

Nutrition 4.0: Technology as an Ally in Pet Nutrition
The pursuit of longevity and quality of life has led pet owners and veterinary professionals to explore new tools. In this context, AI emerges as a resource capable of processing complex data and offering innovative solutions, from personalized nutritional recommendations to the early detection of health issues.
The Technological Revolution in the Pet Sector
The digital world is no longer confined to social media and entertainment; it has made a strong entrance into the pet market. Today, innovation reaches dogs' and cats' food bowls as well. Digital platforms allow pet owners to select specific formulas based on their pet's profile, compare ingredients in real time, and receive personalized menu suggestions. Automated subscription systems ensure food is always available at home, while AI-powered applications help identify which type of diet could improve digestion, skin health, or energy levels. Technology, in this way, not only reorganizes veterinary practices but also redefines how pet food is produced, offered, and consumed.
But innovation doesn't stop there. Wearable devices and smart collars can monitor a pet's heart rate, body temperature, sleep patterns, and activity levels. Data sent in real time to applications can alert owners to behavioral or health changes before they develop into serious conditions.
International studies confirm that the use of digital tools significantly increases the chances of early diagnosis. Detecting a change in sleep or appetite can mean the difference between a simple intervention and a complex treatment.
Personalized and Preventive Nutrition: Data that Saves Lives
One of the fields where AI shows the greatest potential is nutrition. AI can cross-reference data such as age, breed, size, weight, and medical conditions to create customized diets tailored to each animal.
Imagine a senior cat with chronic kidney disease. By entering the information into an AI system, the pet owner receives suggestions for foods with reduced phosphorus content, highly digestible proteins, and supplements that support kidney function. While these recommendations do not replace veterinary consultation, they serve as a practical guide to help owners make faster and more informed decisions.
The same logic applies to common issues, such as skin allergies or gut microbiome imbalances. Well-trained algorithms can identify which ingredients promote skin health or which prebiotic fibers support intestinal balance. Nutrition thus evolves from being generic to becoming preventive, reducing the incidence of diseases and improving life expectancy.
The Pet Owner Experience and Business Innovation
AI also impacts the relationship between pet-sector companies and consumers. Digital platforms can analyze purchasing patterns and offer automated recommendations. If a pet owner regularly buys dog food, the system can suggest add-ons like functional snacks, joint supplements, or wellness accessories.
Beyond convenience, this level of personalization creates an emotional connection between customer and brand, conveying the feeling that each recommendation was uniquely tailored. For companies, the data collected helps identify trends, anticipate product launches, and fine-tune market strategies with greater accuracy.
Innovative startups are already developing virtual assistants that guide users on how to enrich diets with natural ingredients or manage mild symptoms. These systems, by cross-referencing variables like breed, size, and age, can recommend everything from the gradual introduction of vegetables to the use of probiotics. While they do not replace professional advice, they serve as immediate and accessible support for pet owners seeking to improve their animals' quality of life.
Examples of Personalization in Practice
AI's value is best expressed through its ability to generate individualized plans. Some common examples include:
Age: Puppies receive recommendations that support growth, while adult or senior pets are guided to diets adapted to their changing needs.
Breed and size: Formulas can be adjusted to better suit the characteristics of different breeds and sizes, whether in kibble texture, shape, or nutrient balance.
Lifestyle: Very active pets may be directed toward diets with higher energy content, while calmer animals are offered options aimed at maintaining a healthy weight.
In all cases, AI acts as a support tool, accelerating decision-making and bringing pet owners and professionals closer to a more efficient and personalized approach.
Challenges and Limits of Technology
Despite advances, artificial intelligence is not a definitive solution. Algorithms offer responses based on prior data and patterns but still face limitations when dealing with complex clinical conditions that require critical interpretation.
Managing nutrition in cases of comorbidities, for example, requires deep knowledge of physiology and nutrient interactions. While AI-generated diets often align with evidence-based information, gaps remain that only professional expertise and judgment can fill.
Another challenge is the ongoing need for education. It's not enough to digitize processes; both professionals and pet owners must understand how to use technology ethically and responsibly, avoiding over-reliance on automated systems.
A Healthier Future for Pets and a More Practical One for Pet Owners
The future of the pet sector points toward increasing integration between science, technology, and well-being. AI does not replace veterinarians or pet nutritionists, but it does extend their capabilities, enhancing early diagnosis, preventive nutrition, and personalized care.
The future of animal nutrition will be digital but also deeply human. Because behind every data point processed, every recommendation generated, and every alert sent, there is something deeper: the genuine affection of someone who cares for their life companion.
At the intersection of algorithms and affection, science and emotion, a new era is being written—one where animals not only live longer but live better, and where technology becomes an ally in their well-being.

Palatability & Manufacturing: Impact on Pet Preferences
Differences Between Cats and Dogs
To begin the discussion on palatability, we must first understand our main customers: cats and dogs. The variability between these companions —their behavior, eating habits, and nutritional needs— must be considered to satisfy them and encourage pet owners to repurchase their food. Understanding what makes cats and dogs want to eat will help optimize feed manufacturing and achieve greater palatability.
A key difference between cats and dogs is their feeding behavior. Cats are carnivores, while dogs are omnivores, which leads to different nutritional needs and formulas. For example, cats require higher levels and better quality of proteins compared to dogs. FEDIAF recommends between 18% and 25% protein for dogs and between 25% and 33% for cats, which affects the starch content in their recipes and the nutritional values of the food. These differences require adjustments in production parameters to improve palatability.
The sense of taste in cats and dogs, although both are based on a carnivorous pattern, varies significantly. Dogs enjoy sweet and sour flavors, such as carboxylic and phosphoric acids, while cats prefer bitter flavors and are not sensitive to sweetness. Dogs generally consume large meals quickly, possibly due to their pack heritage, and tend to take the food with their teeth and crush it, preferring softer foods. On the other hand, cats eat several small meals a day, mimicking their hunting habits, and use their tongues and molars to break the food, preferring harder and drier foods.
Finally, the sense of smell is a critical factor in palatability for both cats and dogs, with their sense of smell being much more sensitive than that of humans. Cats have twice as many sensory olfactory cells as humans, and dogs may have up to 300 million olfactory receptors compared to about 5 million in humans.
Importance of Ingredients
Improved palatability begins with the proper selection of raw materials. Factors, such as protein quality, freshness, lipid oxidation, and ingredient proportions directly influence the texture and flavor of the food.
In one trial, chicken meal and chicken liver were replaced with hydrolyzed chicken liver in a standard recipe. "Versus" tests showed a clear preference for diets that included the hydrolyzed liver, even with 5% and 10% inclusion rates. Choosing the right protein is, therefore, the first step toward higher food acceptance.
Processing: From Grinding to Drying
The initial processing stages, such as grinding and mixing, affect particle size and product homogeneity. Improper grinding can cause irregularities that negatively impact texture.
In extrusion, starch gelatinization is critical. This process, which begins with the preconditioner, improves food cohesion. Insufficient starch content can cause kibble to disintegrate, while excess increases density. For cats in particular, kibble hardness influences acceptance: they prefer more compact products.
A common challenge is balancing protein and fat levels in cat foods without compromising product expansion. The key is adjusting ingredients to achieve both the appropriate nutritional profile and an attractive texture.
Coating Optimization
Coating is one of the most decisive steps to achieve superior palatability. It is done by applying fat and liquid and/or powdered palatants. Fat, used at levels from 1% to 15%, serves nutritional functions and acts as an adhesive base for palatants. However, fat alone is not enough to ensure high acceptance.
Liquid palatants (1% to 4%) enhance aroma and are more used in dog foods, where higher moisture and softness are sought. On the other hand, powdered palatants (0.5% to 3%) add flavor and moisture control, being common in cat foods, which require low moisture content and high protein levels.
To maximize coating effectiveness, it is recommended to apply fat first, then the liquid palatant, and finally the powder. This ensures better adhesion and homogeneity.
Technical Factors of Coating
Nozzles: The diameter and pressure of the nozzles affect coating quality. Very low pressure generates large droplets that do not disperse well, while excessive pressure produces a mist that can be lost in the air. Proper positioning and spacing ensure uniform coverage.
Mixing: In batch systems, the mixing direction influences homogeneity. Mixing from the outside inward improves palatant distribution, while the opposite creates clumps. Optimizing this process enhances the sensory experience of the food.
Types of applicators: Batch applicators allow greater control, better homogeneity, and adjustments per batch, ideal for super-premium products. Although slower and more expensive, their efficacy in palatability terms makes them preferable in high-end segments. In contrast, continuous applicators are faster and more economical but may have lower precision.
Conclusion
Understanding the unique needs and behaviors of cats and dogs is fundamental to optimizing the palatability of pet foods. Given their distinct feeding habits, nutritional requirements, and sensory preferences, it is clear that a one-size-fits-all approach is ineffective.
The manufacturing process, from grinding to drying, plays a crucial role in determining the texture and palatability of the final product. Proper starch gelatinization, precise mixing, and controlled extrusion and drying processes are essential to achieve the desired consistency and flavor of the food. Each stage must be carefully adjusted to maintain the integrity and appeal of the product, responding to the specific preferences of cats and dogs. Coating, one of the most critical stages to improve palatability, requires careful ingredient selection and application techniques. By optimizing fat and palatant use and ensuring both efficient application and homogeneous mixing, it is possible to develop a much more attractive product.
In conclusion, improving the palatability of pet foods involves a multifaceted approach that encompasses ingredient selection, precise manufacturing processes, and effective coating techniques. By addressing these factors, we can ensure that both cats and dogs receive foods that satisfy their flavor preferences.

Enhancing Palatability: The Role of Pet Food Manufacturing in Pets Preferences
Differences in Cats and Dogs
To begin the discussion on palatability, we must first understand our primary customers: cats and dogs. The variability between these companions —their behavior, eating habits, and nutritional needs— must be considered to satisfy them and encourage pet parents to repurchase their food. Understanding what makes cats and dogs eager to eat will help us optimize kibble manufacturing and achieve higher palatability.
One key difference between cats and dogs is their feeding behavior. Cats are carnivores, while dogs are omnivores, leading to different nutritional needs and formulas. For example, cats require higher protein levels and quality compared to dogs. FEDIAF recommends 18-25% protein for dogs and 25-33% for cats, affecting the starch content in their recipes and the nutritional values of the kibbles.1 These differences necessitate adjustments in production parameters to enhance palatability.
Cats' and dogs' sense of taste, while both based on a carnivorous pattern, vary significantly. Dogs enjoy sweet and certain acidic tastes, like carboxylic and phosphoric acids, whereas cats prefer bitter flavors and are not sensitive to sweetness.2
Dogs typically consume large meals quickly, possibly due to their pack heritage, and tend to grab kibbles with their teeth and grind them, preferring softer kibbles. Conversely, cats eat several small meals a day, mimicking their hunting habits, and use their tongues and molars to break food, preferring harder, drier kibbles.
Lastly, smell is a critical factor in palatability for both cats and dogs, with their sense of smell being far more sensitive than humans. Cats have twice as many smell-sensitive cells as humans, and dogs can have up to 300 million scent receptors, compared to around 5 million in humans.3
It's clear that we cannot produce cat food the same way we make dog food if we aim to satisfy both.
Importance of the Choice of Raw Material and Ingredient for Better Palatability
Let's delve into the pet food manufacturing process to identify ways to enhance palatability.
Before production, it's essential to carefully choose raw materials and other ingredients. Factors like high-quality proteins, lipid oxidation, freshness, and ingredient proportions significantly impact texture. Optimizing palatant choice and application is also crucial.
We tested replacing a certain percentage of non-hydrolyzed chicken meal and chicken liver with the same quantity of hydrolyzed chicken liver in a kibble recipe. The recipe remained identical except for the protein component. To assess pet food preferences, we conducted two-bowl tests, also known as versus tests. In these tests, two bowls were prepared, each containing a different type of pet food. We then measured the amount of food consumed from each bowl to determine the pet's preference. We observed significant improvements in palatability with a 5% or 10% inclusion of hydrolyzed chicken liver (Figure 1). Choosing the right protein is the first step to better palatability.
Figure 1: Palatability of diets Including chicken liver, chicken meal and hydrolyzed chicken liver4.
Oil and fat play a critical role as they are coated on the outside of the kibble first and are linked to freshness and oxidation. For both cats and dogs, palatability generally decreases when free fatty acid levels increase and when signs of oxidation appear. Controlling these factors is essential.
Several microingredients can affect palatability. Some may promote oxidation (e.g., certain minerals), while others can directly boost palatability, like specific sugars, salts, and amino acids.
Each of these components has a direct or indirect impact on the final product's palatability. Understanding and optimizing these elements can lead to better-tasting and more appealing pet food.
Pet Food Processing: From Grinding to Drying
The initial steps of grinding and mixing raw materials and other ingredients significantly affect the homogeneity and particle size of the kibble. In extreme cases, inadequate grinding can leave noticeable grain pieces post-extrusion. Even mild cases of particle size variations within a kibble mixture can alter texture and reduce homogeneity.
After mixing, the ingredients typically move to the preconditioner, where the type and quantity of starch used play a crucial role. During this process, starch gelatinization occurs as starch and water are heated, causing the starch granules to swell and irreversibly absorb water. This gelatinization begins in the preconditioner and continues in the conditioner.
The level of gelatinization is vital for kibble expansion and cohesion. Insufficient starch causes kibbles to fall apart if attempting to reduce density, while higher starch levels increase density (Figure 2). This step is key for both kibble production and palatability, especially for cats but also for dogs. The hardness of dry cat food granules significantly affects their preference, with harder products being more favored by cats according to a study by V. Eles, I. Hullar, and R. Romvari.5
For cat kibble, balancing the necessary levels of protein and fat is challenging, as it limits room for starch needed for kibble expansion and cohesion. Meeting the nutritional needs of cats and dogs while ensuring correct kibble expansion and palatability is essential.
Gelatinization continues during extrusion, playing a determining role. The homogeneity of the dry mix can vary depending on the equipment used, such as a twin-screw extruder, which helps homogenize and increase palatability.
Additionally, kibble shape and size are important considerations. Dogs typically prefer larger kibbles, while cats might struggle with a kibble that is too big for their mouths. Larger kibbles also have less surface area for palatants (for quantity equivalent). Complex shapes may decrease palatability due to the difficulty for the pets to prehend the kibbles.
Figure 2: Impact of gelatinization on the bulk density of the kibbles6.
Post-extrusion, drying is a critical step that must be carefully controlled. Excessive moisture variability in a batch can affect palatability from one bag to another. The market average for optimal dog food palatability is around 8% moisture, balancing food safety and mold prevention. For cat food, the target is closer to 6% moisture, the objective being to have the lowest moisture but without breakable kibbles. Consistent moisture levels within batches allow for better control over palatability. Rapid or excessive drying can negatively affect kibble texture and palatability (drier outside than inside).
Typically, a shifting step after drying and before coating removes the dust and powder (fines) produced after extrusion. These fines negatively impact palatability by being unappealing and causing palatants to be lost, reducing the amount coated on the kibbles.
Pet Food Processing: Coating Optimization
One of the most critical steps in achieving optimal palatability is the coating of fat and palatants. This process can be optimized in several ways.
It's important to remember that the ingredients used for coating vary depending on whether the food is for cats or dogs. Fat, usually applied in amounts ranging from 1% to 15%, serves nutritional purposes and protects the kibbles, often containing antioxidants. Fat helps palatants adhere to the kibble and provides an initial level of palatability. However, fat alone isn't sufficient to significantly boost palatability. In tests without palatants, we found that consumption rates were below average, indicating that neither cats nor dogs were satisfied.
To enhance palatability, we add liquid palatants (1% to 4%) or powder palatants (0.5% to 3%), or both. Liquid palatants enhance aromas and can act as binding agents for the powder. These are mainly used for dog food, given the higher moisture targets and preference for smoother kibbles. As scent is a crucial factor for dogs, aroma plays a significant role. Powder palatants add flavor, help to control the moisture and are typically used for cat food, which targets low moisture and high protein content. Cats have three types of chemoresponsive tongue receptor units, each responding to different compounds that can be found in quantity in powder palatant (amino acid, inorganic salts, nucleotides...)7.
It's generally recommended, though not mandatory, to apply fat first, followed by liquid palatants and then powder palatants to optimize the effectiveness of each component. Adequate amounts of fat and liquid palatants should be used to ensure the powder adheres well to the kibble.
Optimizing the spraying system and mixing processes is vital for effectively applying these ingredients. Here are key factors to consider:
1. Nozzle selection and placement (Figure 3):
The diameter and pressure of the nozzles affect the homogeneity and efficiency of the coating. Larger diameters may cause excess coverage, while smaller ones might not cover all kibbles.
Pressure impacts droplet size. Too low-pressure results in concentrated sprays, while too high pressure creates a cloud, leading to palatant loss.
Nozzles should be spaced adequately to avoid overlap and ensure even coverage. They should also be positioned close enough to reach the kibbles without significant loss of liquids.
2. Mixing process (Figure 4):
In a batch coater with two shafts, mixing from the outside to the inside creates a hill, enhancing palatant coating. Mixing from the inside to the outside creates a hole, leading to clustering and poor homogeneity.
Figure 3: Optimizing coating homogeneity
Figure 4: Optimizing mixing
By carefully selecting ingredients and optimizing application techniques, we can significantly improve the palatability of pet food, ensuring satisfaction for both pets and their owners.
We cannot finish discussing the impact of coating on palatability without addressing the main differences between batch and continuous coaters.
A batch coater generally provides more homogeneity and allows for parameter adjustments from one batch to another. Since it is enclosed, it enables high-rate fat coating (using vacuum coaters) and simplifies the cleaning process. It also helps prevent dustiness during powder coating. However, batch coating is typically slower and more expensive. The main advantage of a continuous coater is its faster process, making it more cost-effective.
In general, batch coating is more recommended when higher palatability is required, especially when producing super premium products.
Conclusion
Understanding the unique needs and behaviors of cats and dogs is fundamental to optimizing the palatability of pet food. Given their distinct feeding habits, nutritional requirements, and sensory preferences, it is clear that a one-size-fits-all approach does not work. The manufacturing process, from grinding to drying, plays a crucial role in determining the final product's texture and palatability. Adequate starch gelatinization, precise mixing, and controlled extrusion and drying processes are essential to achieve the desired kibble consistency and taste. Each step must be fine-tuned to maintain the integrity and appeal of the kibble, catering to the specific preferences of cats and dogs. Coating, one of the most critical steps for enhancing palatability, requires careful consideration of the ingredients used and the application techniques. By optimizing the use of fats and palatants and ensuring efficient spraying and mixing, we can create a more appealing product.
In conclusion, improving the palatability of pet food involves a multifaceted approach that encompasses ingredient selection, precise manufacturing processes, and effective coating techniques. By addressing these factors, we can ensure that both cats and dogs receive food that satisfies their taste preferences.

Pet Food Quality: A More Holistic Approach to Food Safety
Managing Inherent Safety & Quality Risks
Microbial hazards not only threaten pet safety but also create public health risks due to the potential for direct human contact with pet food. To protect their business and brand from risks related to pathogen contamination, pet food manufacturers should implement microbial management strategies throughout the value chain, including:
Implementing Good Manufacturing Practices (GMPs) and Hazard Analysis and Critical Control Points (HACCP) programs
Providing ongoing training to employees on quality, food safety and hygiene practices
Developing regular testing plans on finished products
Maintaining a clean and hygienic production and packaging environment
Sourcing quality raw materials from reputable suppliers and conducting supplier audits
Utilizing treatment intervention strategies to ensure safety and quality compliance
Implementation of these steps is necessary to ensure the safety and quality of pet food and to mitigate recall risks. However, understanding microbial challenges in raw materials, their impact to quality and how to effectively manage them is also vital to maintain freshness, shelf-life and palatability of pet food.
Protecting Your Quality and Investment
Ensuring the safety and quality of pet food is a challenging and complicated process for pet food manufacturers and renderers alike. Variability in raw materials, complex supply chains, and various product formats and processes can lead to oxidative deterioration and microbial contamination in both ingredients and the pet food itself.
Antioxidants are commonly used to manage quality, improve shelf-life, and minimize impact to palatability due to oxidation. However, antioxidants do not help with microbial issues. Managing microbial risks through the value chain (Figure 1) can be just as important as controlling oxidation and, in some situations, can help support the effectiveness of the antioxidant.
Microbial impacts to pet food begin as early as the initial raw material collection, such as when animal processing co-products are converted into valuable protein meals and fats that will become components of a pet food diet. At this early stage, high moisture levels, presence of endogenous bacteria and enzymes and elevated temperatures can lead to rapid microbial growth, hydrolysis of fats and breakdown of proteins.
Hydrolysis of triglycerides results in elevated free fatty acids (FFAs) levels in rendered fats and protein meals, which can impact pet food in two ways – reduced palatability and increased rate of oxidation. It is well known that elevated FFAs can have an undesirable impact on palatability of pet food. Additionally, FFAs are generally more prone to oxidation than trigylcerides1, and thus can reduce shelf-life of rendered fats, protein meals and ultimately finished pet food.
The breakdown of proteins can happen in both rendered raw materials and fresh or frozen meats. Protease enzymes hydrolyze proteins into peptides and amino acids, and amino acids can be further broken down into biogenic amines (BA). In low concentrations, BAs can play an important role in many physiological functions within the body. However, at high concentrations BAs have been shown to negatively impact palatability in both cat and dog food2,3 and may pose risks to animal health.4,5,6
Figure 1: Pet Food Value Chain
An important first step in your food safety plan is to address the microbial quality concerns as early as possible in the process to minimize the downstream impacts on freshness, safety and quality. Using freshness control treatments like ALLINSUR™ and RENTERRA™ can help limit FFAs and control biogenic amine formation in raw materials thereby helping to ensure pet food is safe, high quality, fresh, and nutritious.

How Rendering is Recycling: The Role of Rendering in Pet Food Production
The work that renderers do not only supports sustainability but also plays a vital role in maintaining the safety and quality of the products pet food manufacturers deliver to consumers.
Rendering is, in fact, a form of recycling—a process that converts inedible material from animal production that might otherwise go to waste and converts them into useful, high-quality ingredients. But what exactly is rendering, and how does it contribute to a more sustainable world? In this blog, we'll explore the key facts about rendering and why it's a process that we should all support and understand.
What is Rendering?
Rendering is a highly regulated and specialized process that involves converting animal by-products—such as meat scraps, bones, fats, and trimmings—into useful materials like meat and bone meal, fat, and protein meals. These ingredients are often used in pet food production, livestock feed, biofuels, oleochemicals and even fertilizers.
Roughly 50% of an animal is considered inedible by Americans due to consumer preferences. While these animal by-products are typically viewed as waste by many, rendering transforms them into essential ingredients that support animal nutrition, health, and welfare. It's a process that reduces the environmental footprint of animal agriculture by preventing waste and lowering emissions. Rendering is truly recycling in its purest form, as it takes materials that would otherwise be discarded and gives them a second life.
The Environmental Benefits of Rendering
Rendering not only recycles valuable nutrients but also helps reduce the environmental impact of waste in the food supply chain. According to the North American Rendering Association (NARA), rendering is an efficient way to recover animal by-products and keep them from ending up in landfills, where they could contribute to methane emissions—a potent greenhouse gas.
By turning these by-products into valuable ingredients, rendering reduces the demand for new raw materials, conserves natural resources, and lowers energy consumption. Each year, renderers recycle and repurpose approximately 31.4 billion pounds of fat, oil, and protein products into nutritious pet food, biodiesel, and countless other useful items — making rendering one of the most sustainable ways to reduce food waste.
Facts About Rendering: A Deeper Look
Rendering is often underappreciated, so let's dive into a few key facts about the process and its many benefits, many of which are supported by NARA:
Rendering reduces waste: By recycling animal by-products, rendering prevents them from entering landfills, thus reducing the overall waste burden on the environment. These by-products can come from food processing plants, slaughterhouses, and even restaurants and grocery stores, all of which contribute to the massive amounts of inedible waste with the potential to be upcycled into valuable sources of fats and proteins.
Rendering is safe and regulated: The rendering industry is highly regulated by government agencies such as the U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA). This ensures that rendered products meet strict safety standards and are safe to use in pet food, livestock feed, and other products.
Rendering is a key ingredient supplier for pet food: Many pet food ingredients—such as meat and bone meal, poultry by-product meal, and a variety of animal fats—are the result of the rendering process. These high-quality ingredients provide essential nutrients that keep pets healthy and nourished.
Rendering supports sustainability: The rendering process is an integral part of the sustainability of animal agriculture. By converting waste into useful products, rendering helps reduce the need for additional natural resources, conserving water, land, and energy.
Rendering helps reduce carbon footprint: The rendering industry is a significant player in reducing the carbon footprint of food production by ensuring that food and animal agriculture waste is converted into usable products rather than releasing harmful gases like methane into the atmosphere.
For more detailed facts on rendering and its importance to sustainability, we encourage you to visit NARA's Facts about Rendering page. The organization provides a wealth of information on the many ways rendering contributes to reducing waste and supporting sustainable practices in the pet food and agriculture industries.

Sustainable management at Kemin Nutrisurance: Reduce, recycle, reuse
At Kemin Nutrisurance, we are constantly committed to sustainability by adopting practices aligned with Sustainable Development Goals (SDGs), adopted by the United Nations, and implementing initiatives that seek circularity and align with the 3Rs. In the article, we will explore each principle, highlighting its importance and application in our company. Reducing: minimize waste Reducing waste is the base of our sustainability strategy. In 2023, we adopted various actions to minimize the amount of waste that ends up in landfills. Our guidelines to manage waste are in our Solid Waste Management Program which aligns with the current Ambiental law. These guidelines not only help to prevent soil, air, and water pollution but also an efficient management of resources. In June 2023, we began to allocate sludge from the effluent treatment plant, organic waste from the production process, and ashes from the kettle to a compost-specialized company. As in Figure 1, the process results in the production of a soil conditioner that gives added value to the waste. In 2023, these actions diverted over the 60% of waste that would end up in landfills, minimizing the need for new landfills and benefiting the soil. Figure 1: Picture of waste circularity Recycling: turn waste into resources Kemin Nutrisurance also stands out for its recycling area. In 2023, we raise awareness among our collaborators about the importance of recycling through awareness campaigns on waste and recycling. Our recyclable waste, such as plastic, paper, and craft from the packaging of raw materials and supplies are sent to a recycling plant. We have agreements with specialized companies to ensure the correct destiny and direction of recyclable waste. We developed the social program Proyecto Nuevos Caminos: Nutriendo el Mañana, visit the link https://info.kemin.com/pt-br/projeto-novos-caminhos for a better understanding. One of the bases of the program is to promote recycling, especially of plastic covers, and allocate financial resources to an institution that takes in children and teens in vulnerable situations. For two years, 2022 and 2023, we were recognized for this social responsibility initiative. In support of the program Proyecto Nuevos Caminos, we received the Empresa Ciudadana certificate and sign from the Public Ministry and State Court of Justice of Santa Catarina. Reusing: maximum exploitation of resources Reusing resources is essential to sustainability. In 2023, we opened up a new Effluent Treatment Station (ETS). This new structure, made with an activated sludge system, uses modern and efficient process. The new ETS multiplied by five the treatment capacity compared to the old one, generating better quality effluent. Thinking of the efficiency in the use of resources, we have an effluent reusing system and a fertigation system. After the treatment, the effluent is sent through a fertigation system to the agricultural land area. In this way, we reuse 100% of the treated effluent, promoting the resources reusing and contributing to the improvement of the soil and crops. SDGs 6 – Clean water and sanitation Our effluent management practices are aligned with the SDGs 6 that aim to improve water quality by 2030. We invested in a new Effluent Treatment Station in order to treat our industrial effluent, which entered into operation in 2023 compared to the old one. Besides using a treatment process that generates a better treated effluent, the current ETS has multiplied by five the treatment capacity. At the same time, it delivered maximum efficiency removing 99% of the concentration of biochemical oxygen demand (BOD). After the treatment, 100% of the effluent is reused in agricultural land areas through a fertigation system. SDGs 12 – Responsible consumption and production Reducing, recycling, and reusing are practices that align with SDGs 12 goal 12.5 that aim to substantially reduce waste generation by 2030. In 2023, we significantly reduce the delivery of waste to landfills, minimizing places for elimination, and adding value to the generated waste. As a result of our circularity initiatives, we also succeed in diverting 60,27% of landfill waste. SDGs 13 - Action to combat climate change In 2023, 100% of the consumed energy at Kemin Nutrisurance was clean and certified. It came from renewable sources and was bought at the electricity market, which is aligned with SDGs 13 goal 13.3, aiming for climate change mitigation. During the same year, we implemented a new kettle by biomass burning. Besides having higher levels of atmospheric emissions at environmental levels, it has the purpose of reducing liquefied petroleum gas (LPG) consumption. This improves atmospheric emissions rates and reduces fossil fuel consumption. Considering scope 1 and scope 2 emissions, our emissions were 6,692 t CO2eq and 4,371 t CO2eq by 2022 and 2023. Compared to 2022, we will reduce greenhouse gas (GHG) emissions by 34.7% in 2023. Our reducing, recycling, and reusing practices are integrated into each operation. We will continue innovating and implementing actions that promote sustainability, ensuring the reduction of our environmental impact and the responsible use of resources for a sustainable future.

Wet food

Wet Pet Food Quality
Wet pet food is a popular choice among pet owners, with more than 6.5 billion kgs sold in 2022¹. Pet owners often see wet pet food as a more premium option than traditional dry kibble diets.
They expect their preferred wet pet food brand to be palatable to their pets and have the same appealing aroma, color, and texture every time they open a can or pouch. Consistency in these qualities is particularly important for pet food manufacturers to maintain their brand image. Flavor, aroma, color, and texture can be affected by key parameters of pet food production, including processing conditions, pH, grind size, and thickeners.
Kemin: Your partner in wet pet food
Testing solutions in wet pet food is more complex than in dry foods. Kemin has invested in a wet pet food pilot facility to provide partnership opportunities with customers seeking solutions to their wet pet food challenges.
This facility is used to build pilot-scale wet pet food batches of loaf or chunk in gravy formulas in cans, trays, and pouches. This facility offers an opportunity to leverage Kemin's expertise across the value chain to help address several key challenges, including palatability, biogenic amine formation, and color retention.
At Kemin, we care that our solutions work in pet food matrices and have minimal impact to product integrity and quality standards. Therefore, pilot-scale wet pet food runs can be tested for many success criteria, including palatability, texture, viscosity, pH, color, weep, and aroma analysis, depending on customer needs.
The right texture
While each wet pet meat dough manufacturing process may be unique, it has been observed that meat grind and disintegration quality affect loaf pâté texture or hardness. It has been observed that cats preferentially eat diets with significantly softer loaf pâté texture versus a harder one. Pet parents may also prefer the look of a softer loaf pâté versus a hard, brittle one². Loaf pâté quality is a metric Kemin measures on diets manufactured at their Wet Pet Food Pilot Plant.
Kemin Texture Testing³. A texture analyzer with a ball probe can simulate the feel of meat in an animal's mouth and on their model diet. Diets with various meat cutting shear were manufactured at the Kemin Wet Pet Food Pilot Plant and compared to a commercially available Turkey and Giblet Loaf Pâté diet using Tukey Honest Square Differences statistical analyses, with a p-value less than 0.05 to distinguish texture differences.
The Turkey and Giblet Loaf Pâté recipe with minimal meat grinding and cutting shear had a significantly harder loaf pâté than two times and three times more shear [Figure 1]. Compared to desired texture of the benchmark loaf pâté diet, it is observed that too little cutting shear created a significantly harder loaf pâté. Using two times and three times more cutting shear made similar texture hardness to benchmark loaf pâté.
Achieving the ideal "look"
Just like cooking a steak or chicken breast releases juices, meats in a wet pet diet release water during sterilization cooking through the retort process. Meat scientists refer to these juices as weep, syneresis or expressible moisture. Loaf pâté diets sometimes have too much liquid weep, which may thin out the gravy or gel. Too much weep can adversely affect consumer perception, as some consumers view quality wet pet diets as having thick liquid like a gravy or gel.
Often thickeners like starches, gums, and proteins are added to diets and special processing is used to enhance soluble proteins and reduce liquid weep. Literature from Kansas State University confirmed that wet pet diets containing only the ingredients necessary for complete and balanced nutrition may be too thin to rapidly fill cans, have sedimentation challenges, and express too much liquid after sterilization cooking. The type and quantity of thickeners must be balanced to achieve the right 'look', including the right amount and thickness of the liquid in a wet diet. Both 'Thick to Thin' and 'Thin to Thick' ingredients are necessary.
'Thick to Thin', Guar gum is a popular ingredient to add to nutritious wet pet meat doughs to thicken it, maintain a homogenous mixture, and to rapidly fill cans. After sterilization cooking, wet pet diets with added guar gum resemble diets with no guar gum. In other words, viscosity and thickness provided by guar gum assists in cooking but not to maintain a thick liquid after cooking.
'Thin to Thick', Other thickeners, gums, and proteins are added to nutritious wet pet meat doughs to enhance their qualities after sterilization cooking. These gums are considered 'Thin to Thick' ingredients, among them kappa carrageenan, xanthan gum, and locust bean gum. These thickeners offer some viscosity before the cooking step but have been observed to thicken remaining liquid and to significantly reduce liquid after sterilization cook.
Overall palatability
After optimizing look and texture, the last step is to ensure that the wet diet is palatable enough to encourage enthusiastic consumption by the target customer- the pets. There are many factors that impact palatability including texture, ingredient type and quality, processing and the type of palatability system that is used.
Freshness + Palatability. Ingredients are carefully selected by availability, quality, price, flavor, and processability to meet market needs. Many wet pet manufacturers use both fresh and frozen meats to make their product, which has advantages and disadvantages. Frozen meats have a significantly longer shelf-life and provide ingredient flexibility and availability. On the other hand, frozen ingredients can be difficult to grind or disintegrate, require more energy to activate than fresh meats, and require storage management. Fresh meats can be less expensive and are easier to process than frozen but are difficult to preserve more than a few days and challenging to minimize microbial growth. Aged, fresh meats grow micro-organisms which impact meat dough quality by developing biogenic amines and shortening mandate time – the time between seaming cans and starting sterilization cook process – for wet pet manufacturers. Figure 2 shows that cats prefer lower biogenic amine diets, which can be achieved by using fresher meat or utilizing an antimicrobial treatment to help maintain fresh character.
Use of a Palatability Enhancer. Wet pet food is often perceived to be highly appealing to cats, but some cats may be reluctant or refuse to eat a diet altogether. Pet food manufacturers can elevate the profile of wet cat food diets by adding palatability enhancers to the finished diet. Figure 3 shows that the addition of a dry palatant in the chunk component of a chicken-based chunk and gravy diet was statistically preferred to a control diet with no palatant. Palatability performance increases with increasing palatant application rate. All rations were made in the Kemin pilot plant.
Moreover, palatant addition to the wet cat diet can transform an amalgam of animal proteins into a product with a clean, unified consumer aroma. Palatants tested in the Kemin Pilot Plant have changed the perception of cat wet pet diets from one that is gamey or pungent to more pleasant meaty flavors or aroma typical of the retorted foods industry.
CONCLUSION
There are many factors that can influence the overall consumer experience of a wet pet food brand. Understanding how to make a consistent, appealing product is key to satisfying loyal customers and further gaining market share with new customers. Pet food manufacturers should consider the value of partnering with suppliers that understand the complexities of wet pet food production and make solutions tailored to their specific needs.

Kemin introduces new palatant line for wet cat food formulas
DES MOINES, IOWA — Kemin Nutrisurance, the pet food and rendering segment of Kemin Industries, recently announced a new line of palatants for use in wet cat food: PALIVATE™. With increased consumer awareness of pet health, many have switched their pets to more appetizing meals, like wet formats, which are often considered to be highly palatable. According to data shared by Kemin and reported by Euromonitor, cat owners choose wet formulas almost as often as dry ones, with wet cat food comprising 44% of the global volume of cat food. Although wet cat food is believed to be highly palatable, many consumers and pet food processors have struggled to get a cat to consume wet food, according to Kemin. Kemin's new PALIVATE palatants are designed to increase palatability of wet formulas while minimizing negative effects to a formula's overall integrity. The PALIVATE line can withstand retort processing and can be used for formats with low inclusions, including loaves and chunks in gravy. According to testing conducted by Kemin, the addition of PALIVATE in chunks in gravy formats increased a cat's overall intake of the food. The dry palatants also significantly outperformed a competitive palatant when used in chicken- and salmon-based loaf formulas, according to the company. By Nicole Kerwin - Pet Food Processing

Kemin Industries, a global ingredient manufacturer that strives to sustainably transform the quality of life every day for 80 percent of the world with its products and services, is celebrating 25 years of growing its proprietary line of rosemary to create sustainable solutions for foods. Kemin pioneered the use of rosemary molecules in ingredients in the late 1990s and has since established itself as a leader in the market. 'The Kemin team is incredibly excited to celebrate this major milestone, and we are proud to offer our partners solutions that come from our sustainable, vertically integrated rosemary program,' said Dr. John Greaves, Vice President of Specialty Crops, Kemin Industries. 'Being one of the first suppliers in the marketplace, we have dramatically evolved our offerings and continuously improved the production of these specialty crops over the last 25 years.' Today, rosemary is recognized alongside tocopherols as a major component in maintaining natural freshness and flavor. As one of the largest vertically integrated producers of sustainably grown rosemary, Kemin offers a well-tracked supply chain and can trace its crops from cuttings to final product. The company's proprietary rosemary is formulated into effective clean-label solutions to help keep food fresher, safer and more flavorful. Prior to the innovation and initial investment by Kemin in developing its own vertically integrated rosemary program, the plant was mainly wild harvested in southern Europe and North Africa. 'We quickly realized wild harvesting was not sustainable, and we needed to put a rosemary cropping system in place to improve biomass through plant breeding. Kemin developed one of the first rosemary-breeding programs, which took the plant from a Mediterranean evergreen shrub to a high-performance 'phytochemical manufacturing plant',' said Greaves. 'Our scientists analyzed and selected the most potent lines of rosemary from around the globe,' said Greaves. 'Then, our team used conventional plant-breeding methods to begin a continuous improvement program, which resulted in one of the largest collections of rosemary in the world.' Demand for products with simple labels and natural ingredients has skyrocketed, and sustainability in ingredients continues to drive growth. According to Mintel, 42 percent of U.S. consumers feel a strong sense of responsibility to live more sustainably. Kemin rosemary crops are CSCS Sustainably Grown® certified by SCS Global, a certification that recognizes leadership in environmental stewardship, social responsibility and economic stability. 'As we look to the future, Kemin continues to invest in innovation as our scientists and growers work together to discover new molecules for new natural antioxidants,' said Greaves. 'We are actively developing new botanical sources of antioxidant molecules to complement rosemary-based formulations and are continually working with extraction and formulation methods to produce the most effective rosemary products.'
