Rethinking Protein in Pet Nutrition: From Traditional Sources to Alternative and Functional Proteins

In recent years, however, the discussion around protein has expanded significantly. Terms such as 'alternative proteins', 'novel proteins', and 'functional proteins' are increasingly used across the food and pet food industries. Much of this interest is driven by sustainability concerns and projections that global demand for protein will increase substantially as the human population approaches 10 billion by 2050 (FAO, 2022; OECD-FAO, 2023).
  This raises an important question: do we truly need entirely new protein sources to feed our pets, or should we focus on improving how we utilize the protein sources we already have?
  The answer likely lies somewhere in between. Traditional protein sources remain nutritionally robust, while emerging technologies and alternative ingredients offer opportunities to improve sustainability, functionality, and health outcomes—including effects on the gut microbiome.
Global Protein Demand and the Sustainability Debate   Projections toward 2050 suggest that global protein demand will rise sharply as the world population approaches 10 billion, with food demand expected to increase by about 60% (FAO 2018; FAO 2022; Henchion et al., 2017). At the same time, the global pet population continues to expand, with an estimated 900 million dogs and cats worldwide. Approximately 60% of these animals are concentrated in Europe, the United States, China, and Brazil.
  These trends have raised concerns about whether traditional livestock production alone can meet future protein needs. Critics often argue that feeding animal-derived proteins to pets competes with the human food supply and contributes to environmental pressures, such as land use, greenhouse gas emissions, and water consumption.
  However, the picture is more nuanced. A significant portion of animal-derived ingredients used in pet foods originates from rendered co-products of the human food system, including organ meats, trimmings, and fish processing residues. These ingredients represent an efficient form of nutrient recycling within the food supply chain (Boland et al., 2013).
  Advances in food processing technologies are also improving nutrient utilization, enabling greater recovery of proteins, peptides, and bioactive compounds from raw materials and by-products (Yuan et al., 2025). Improving how proteins are processed and utilized may therefore be as important as identifying entirely new protein sources.   Protein Requirements in Dogs and Cats   Protein requirements in companion animals are well established through decades of nutritional research. According to AAFCO guidelines (AAFCO 2026), the minimum protein requirement for adult dogs is approximately 18% on a dry matter basis, while growing puppies require 22.5%. Cats, as obligate carnivores, require higher protein intake, with minimum levels of 26% dry matter.
  In commercial diets, however, protein levels are typically higher. Many dry dog foods contain 22–32% protein, while cat foods often range from 30–40% protein. These levels reflect both nutritional needs and consumer expectations, as protein content has increasingly become associated with perceived diet quality.   Traditional Protein Sources: Still the Foundation   Animal-derived proteins remain central to pet nutrition because of their balanced amino acid profiles and high digestibility. Common ingredients include chicken meals, beef and lamb meals, fish meals, fish protein concentrations, and meat or organ by-products. These ingredients supply essential amino acids, such as lysine, methionine, and taurine and typically exhibit digestibility values around 85–90%, although digestibility can vary depending on the specific ingredient and processing conditions.
  Plant proteins also play a significant role in modern formulations. Ingredients such as soybean meals, pea protein, lentils, and chickpeas contribute valuable amino acids while offering flexibility and cost efficiency in formulation.
  Recent innovations in food processing have further improved plant protein functionality. Technologies such as fermentation, enzymatic hydrolysis, and advanced milling can increase digestibility while reducing anti-nutritional factors such as lectins and protease inhibitors (Yuan et al., 2025).
  These developments highlight an important point: innovation does not always require entirely new ingredients—sometimes it involves improving how existing ingredients are processed and utilized.   The Rise of Fresh and Minimally Processed Meat Ingredients   Over the past decade, the use of fresh meat or poultry has expanded significantly in dry pet food formulations. Many premium kibble products now incorporate fresh chicken, beef, or fish as part of their protein systems.
  In many cases, these fresh ingredients originate from mechanically deboned meat (MDM) or automated meat recovery (AMR) processes, which efficiently recover edible muscle tissue from carcasses after primary cuts have been removed. These ingredients provide highly digestible protein while improving palatability and consumer perception.
  Marketing narratives around 'fresh' ingredients have also been reinforced by the rapid growth of fresh and lightly cooked pet food formats. The fresh pet food market in the United States alone is estimated to exceed USD 3 billion and continues to grow (Packaged Facts, 2023). This trend illustrates how consumer expectations increasingly influence ingredient selection and processing strategies in the pet food industry.   The Rise of Alternative Proteins   While traditional proteins remain dominant, several emerging protein technologies are gaining attention.
  Insect Proteins
Insects, such as black soldier fly larvae, mealworms, and crickets are being explored as sustainable protein sources. Insect meals typically contain 40–65% protein and can be produced using relatively small amounts of land and water compared with conventional livestock production (van Huis, 2021).
  Insect proteins may contain bioactive compounds such as antimicrobial peptides and chitin that could influence immune function and gut health (Gasco et al., 2020). However, scaling production and achieving widespread consumer acceptance remain challenges.   Fermentation-Derived Proteins
Fermentation technologies represent another promising pathway. Microbial fermentation can produce single-cell proteins (SCP) using yeast, bacteria, fungi, or microalgae grown on various substrates (Matassa et al., 2016). These proteins can provide favorable amino acid profiles while requiring relatively small land footprints.
  Traditional fermentation methods—such as koji fermentation using Aspergillus oryzae—can also transform plant substrates into more digestible and nutritionally enhanced ingredients (Yuan et al., 2025). Advances in biotechnology now allow engineered microbes to produce specific peptides or proteins with targeted functional properties.   Cell-Cultured Proteins
Cellular agriculture represents one of the most technologically ambitious approaches to protein production. By culturing animal cells in controlled environments, it may eventually be possible to produce meat without traditional livestock production (Post, 2012). Although promising, this technology is still in its early stages—particularly for pet food applications—and faces challenges related to cost, energy use, and regulatory frameworks.   Protein and the Gut Microbiome
One of the most exciting areas linking protein nutrition and health is the gut microbiome.
  The gut microbiota plays a central role in digestion, immune function, and metabolic health in companion animals. Diet composition—including protein source and digestibility—can significantly influence microbial communities in the gastrointestinal tract (Handl et al., 2013).
  Highly digestible proteins reduce the amount of undigested nitrogen reaching the colon, minimizing the production of undesirable fermentation by-products, such as ammonia or biogenic amines.
  Conversely, certain peptides and amino acids may serve as substrates for beneficial microbial populations, contributing to the production of short-chain fatty acids and other metabolites that support intestinal health (Sandri et al., 2017).   Key Takeaways   The conversation around alternative proteins often frames the issue as a replacement of traditional proteins. Actually, the future of protein in pet nutrition will likely be more integrated and from this discussion, several key insights emerge:
  Traditional protein sources remain nutritionally efficient. Animal and plant proteins continue to provide reliable amino acid nutrition and will remain foundational ingredients in pet food.
  Alternative proteins expand the toolbox; insects, microbial fermentation, and cellular agriculture may complement existing protein systems.
  Processing technology and advances in fermentation, enzymatic modification, and ingredient recovery can improve nutrient utilization, reduce anti-nutritional factors, and enhance the functional value of protein ingredients.
  Consumer expectations are reshaping protein systems. The growth of fresh, minimally processed, and high-protein pet foods illustrates how market trends increasingly influence ingredient selection and processing technologies.
  Ultimately, the goal should not be to replace traditional proteins with alternatives but to develop a diverse and efficient protein ecosystem that supports sustainability, nutrition, and pet health. The key question is not only which proteins we choose, but how intelligently we use them. By Juan Gómez-Basauri, Ph.D. - MAGELLAN LLC

The Protein Matrix: Balancing Formulation, Operational Realities, and Consumer Demands

By Felipe Martínez R.

Today, as pets are increasingly humanized and elevated to the status of family members, the scrutiny placed on the ingredients in their bowls has never been higher. This is why, for this edition, I'm taking a different approach from my past articles and decided to write about the most scrutinized, expensive, and dynamic component of any pet food formula: protein.

The true value of a raw material is no longer dictated solely by its price per ton. Instead, it is defined by a complex matrix of nutritional efficacy, marketing appeal, and manufacturing viability. The universe of ingredients is expanding rapidly, introducing alternative proteins, functional extracts, and novel additives. However, to truly understand how these ingredients deliver value, we must examine how the menu of ingredients, including the different protein sources, complement each other in three dimensions: nutrition, consumer trends, and the realities of managing these materials on the factory floor.
Nutrition: How Proteins Complement Each Other
From a purely nutritional standpoint, a pet does not require specific ingredients; it requires specific nutrients. The goal of any formulator is to deliver a complete and balanced amino acid profile, alongside high digestibility and bioavailability, and palatability—because if the pet does not eat the product, all the effort has been done for nothing. Achieving this is rarely accomplished efficiently with a single protein source. Instead, formulation is all about complements.

Traditional animal protein sources, including chicken, beef, fish, and lamb meal, have long been the workhorses of the industry, offering high protein density and excellent palatability. However, they are often complemented with each other and with plant-based options, such as peas, soybeans, potatoes, or corn gluten meal.

Why blend them?  Because what one ingredient lacks, another provides. For instance, plant-based proteins can be highly digestible and lower the overall ash content of the formula, but they may be limited in essential amino acids (methionine or taurine precursors). By strategically pairing it with a marine protein source, such as salmon meal or a functional extract like yeast, a formulator can bridge the amino acid gap while maintaining a specific price point and functional target.

Furthermore, the rise of alternative proteins, including insects, single-cell proteins, and cultivated meats, is altering the formulation landscape. These ingredients are not just novelties; they can offer functional benefits, such as hypoallergenic properties or high levels of antimicrobial peptides. They 'play' within a formula, not just as bulk protein, but as functional additives that elevate the nutritional profile and the true value of the end product.
The Marketing Push: Premiumization and the Clean Label
While formulators focus on amino acids, digestibility, bioavailability, and palatability, the focus of marketing departments and consumers is the ingredient list and the product claims. In today's premium and super-premium segments, communication trends heavily influence product design, sometimes at odds with traditional formulation logic.

The push for 'clean label' products and limited ingredient diets is a prime example.  Higher-value segments are demanding shorter ingredient lists, driven by a consumer perception that fewer ingredients equate to a more natural, wholesome, and transparent product. This creates a significant challenge: how do you deliver a perfectly balanced amino acid profile when your marketing brief restricts you to a single protein source and a single carbohydrate source?

This restriction has driven the industry toward novel proteins. These new ingredients, such as rabbit, kangaroo, wild boar, herring, venison, and duck, are commanding premium prices—they serve a dual purpose. First, they are highly effective for pets with suspected food sensitivity or allergies to common proteins like poultry or beef. Second, they provide a powerful narrative for marketing and communication. Novel proteins instantly differentiate a brand on a crowded retail shelf, communicating exclusivity and premium quality.

However, the true value here also hinges on the traceability of origin. Consumers put value into knowing that the rabbit was sustainably sourced or if the salmon was wild. Traceability has evolved from a supply chain buzzword into a non-negotiable consumer demand and a core pillar of a brand's value proposition. The story behind the ingredient is now just as important as the ingredient itself.
The Factory Floor Reality: Navigating Production Pain Points
A recipe can look perfect on paper and test brilliantly in a consumer focus group, but it must be feasible to manage within an existing manufacturing process. Managing diverse and novel proteins in a high-volume factory introduces pain points that question the concept of "true value."

One of the most persistent challenges is managing the natural variability of raw materials, particularly animal by-product meals. Meat and bone meals, for instance, can vary significantly from batch to batch depending on the rendering process and the exact source materials. A classic factory pain point is color variation. If a specific batch of chicken meal contains a higher concentration of blood, the resulting kibble will be noticeably darker. While the product remains entirely safe and nutritionally sound, this visual inconsistency can inevitably lead to consumer complaints. Pet owners are conditioned to expect absolute uniformity, and a dark batch of kibble is often misinterpreted as burnt or spoiled. Managing this requires strict supplier specifications, advanced mixing techniques, and sometimes, the reluctant use of colorants to standardize the final appearance.

Beyond color, different proteins behave differently during extrusion. Plant proteins often require different specific mechanical energy and moisture inputs compared to animal proteins. High levels of fresh meat, while highly appealing on an ingredient label, introduce massive amounts of water into the formula, which must be managed to ensure the kibble expands properly and dries to a safe moisture level to prevent mold.
Conclusion: Redefining True Value
The universe of pet food ingredients is undoubtedly expanding, but 'true value' is not found simply by adding the newest, trendiest protein to a formula. True value is achieved at the intersection of three distinct disciplines.

It requires the formulator's skill to blend complementary amino acid profiles for optimal animal health. It demands the marketer's insight to select ingredients that resonate with consumer demands for transparency, limited ingredients, and sustainable origins. And crucially, it relies on the factory expertise to handle the physical realities, variabilities, and organoleptic challenges of processing raw materials at scale.

As the industry continues to innovate beyond price, the brands that succeed will be those that master this complex matrix, ensuring that every raw material earns its place in the bowl: nutritionally, commercially, and operationally. By Felipe Martinez R.

Black Soldier Fly Larva Meal: A Sustainable and Functional Protein Source for Pet Food

By Josiane Volpato

A New Scenario for Proteins in the Pet Food Industry   In this scenario, the pet food industry has been looking for alternatives that simultaneously meet nutritional, technological, and environmental requirements, promoting innovation without compromising the quality of the final products.
  Among the main trends, the partial or total replacement of traditional protein sources, such as poultry viscera meals, meat and bone meal, fish meal, and soybean meal, with more sustainable ingredients with less environmental impact stands out. In this context, black soldier fly larva meal (Hermetia illucens or BSF) has gained prominence as a promising solution to the current challenges of the production chain.
  The production of this ingredient is directly related to the ability of the larvae to convert organic waste into biomass of high nutritional value. This process, known as bioconversion, allows the use of agro-industrial by-products, reducing waste and contributing to circular economy models. In this way, BSF flour not only meets nutritional demands but is also part of a broader sustainability strategy in the pet food sector.
  From a nutritional point of view, BSF flour has a variable protein content, usually between 35% and 60%, depending on the substrate used in the larvae and the industrial processing applied. Although this content is considered intermediate compared to some conventional sources, the ingredient stands out for the quality of its protein and amino acid profile, suitable for the nutritional requirements of dogs and cats.
  In addition, BSF flour has a high lipid content, especially lauric acid, a medium-chain fatty acid associated with antimicrobial properties and potential benefits to intestinal health. This differentiated lipid composition can contribute not only to the energy value of diets but also to important functional effects in the animals' bodies.     Recent studies also indicate additional benefits associated with the use of BSF flour in extruded diets, including improvements in skin integrity, coat quality, and antioxidant response. These effects are possibly related to the presence of bioactive compounds and the quality of the nutrients present in the ingredient.
  Another relevant point is the presence of minerals, such as calcium and phosphorus, at significant levels, as well as essential amino acids, e.g., methionine and tyrosine. The higher concentration of tyrosine, in particular, has been highlighted as a differential of BSF flour, reinforcing its nutritional potential in complete formulations.
  In addition, BSF flour contains compounds with potential prebiotic and antibacterial action, which can contribute to the modulation of gut microbiota and the maintenance of digestive health. This set of characteristics makes the ingredient attractive not only as a source of protein but also as a functional component in diets for dogs and cats.
  Because it is an alternative protein and still little used on a large scale, BSF flour also has potential application in hypoallergenic diets, being an interesting option for animals with food sensitivities to conventional proteins, such as chicken, beef or soy.   Digestibility: The Critical Point of Formulation for a Sustainable Future in Pet Food   Digestibility is one of the main criteria for evaluating the quality of new ingredients in animal nutrition. In this aspect, BSF flour presents consistent results, with protein digestibility coefficients similar to those observed in diets formulated with traditional ingredients.
  Studies indicate that inclusion levels ranging from 5% to 20% result in apparent protein digestibility of 83% to 84%, values compatible with those observed in conventional diets. These results demonstrate that the ingredient is efficiently used by the animals' bodies, without compromising fecal quality.
  In addition to the protein fraction, the lipid digestibility of BSF flour is also noteworthy, being frequently high due to the presence of medium-chain fatty acids, which are easier to digest and absorb when compared to long-chain fatty acids.
  The presence of chitin, a structural polysaccharide in the exoskeleton of larvae, represents another important aspect from a nutritional point of view. Chitin can act as a functional fiber, contributing to the modulation of the gut microbiota and the formation of stools with better consistency. However, its effect depends directly on the level of inclusion and processing of the ingredient, and can, at high concentrations, interfere with the digestibility of nutrients.
  Thus, the use of BSF flour requires an adequate balance in the formulation of diets, in order to maximize its functional benefits without compromising nutritional use.     Palatability and Acceptance by Animals    Another determining factor for the practical application of the ingredient is palatability. The acceptance of food by animals is one of the main indicators of commercial success, especially in diets for cats, which have more selective feeding behavior.
  In general, the inclusion of BSF flour does not compromise the intake, and good acceptance is observed in both dogs and cats. However, studies indicate that this factor is strongly dependent on the level of inclusion.
  Lower levels of substitution, such as 3%, maintain intake similar to the control diet and may even stimulate the animals' initial interest in the food. On the other hand, higher levels, such as 6%, tend to reduce intake and preference. This effect may be associated with the lipid composition of the larvae, especially the higher content of medium-chain fatty acids, which can influence the sensory perception of food.
  Thus, the definition of the appropriate level of inclusion is essential to ensure the acceptance of the final product, with moderate inclusion being the most suitable strategy for commercial formulations.
  In addition to the nutritional and functional aspects, BSF flour has significant environmental advantages when compared to traditional protein sources. Its production requires less use of natural resources, such as water and agricultural areas, in addition to resulting in lower greenhouse gas emissions.
  The ability of larvae to convert organic waste into high-value protein allows the use of by-products that would otherwise be discarded, contributing to the reduction of the environmental impact of the production chain.
  Another important point is production efficiency. Insect farming has better feed conversion and lower need for inputs when compared to conventional livestock, making it a viable alternative for more sustainable production systems.
  This set of characteristics positions BSF flour as an ingredient in line with the main global trends in the pet food industry, which seeks to integrate nutritional performance, innovation, and environmental responsibility.
  In conclusion, black soldier fly larva meal consolidates as a strategic ingredient for the pet food industry, bringing together nutritional quality, functionality, and environmental benefits. Its use allows the development of more sustainable diets without compromising digestibility, fecal quality, or acceptance by animals, representing a promising solution for the future of dog and cat nutrition.

From Alga to Bowl: Astaxanthin Supports Pet Health 

Owing to the ongoing anthropomorphism of pets, owners are taking a closer look at what they're feeding their beloved companions. Just as they themselves are opting for healthier and cleaner-label nutrition—and starting to consider the associated environmental aspects—, owners want to ensure that the same standards apply to their pet's meals. This is manifesting as a shift towards providing fresh food or preferentially selecting more natural or organic pet food products.

Overall, the pet food sector is witnessing continuous growth. The market size in Europe is estimated to be worth $55 billion in 2024 and is expected to reach a value of more than $78 billion by 2029 (growing at a CAGR of approximately 7%).1 Next to classic feed compounds, such as grain or meat, novel functional ingredients are gaining traction in this developing market. Many of these components can be both integrated into feed grades as well as pet-friendly nutraceuticals. One example is carotenoids, which are not only known for their vibrant yellow, orange, or red colours, but also for their antioxidant attributes. One carotenoid with a particularly high antioxidant power—110 times more than vitamin E—is astaxanthin. 

In nature, the most abundant source of astaxanthin is a tiny microalga called Haematococcus pluvialis. Although astaxanthin has a long history as an ingredient in human supplements, its beneficial effects were first discovered in the marine world regarding the survival and reproduction rates of salmon. Research on astaxanthin in aquaculture was also the basis for the Swedish company, AstaReal's business. The organisation was the first to produce natural astaxanthin on an industrial level and, as the subject of more than 70 clinical studies on humans and animals, it owns today's most researched astaxanthin brand in the market.
Species-Specific Research
'We wanted to understand what this might mean for different kinds of animals, so we started using the ingredient in trials with cats and dogs,' says Peter Ahlm, Head of Marketing & Sales at AstaReal. Distinct research on targeted animals is indispensable when it comes to developing a safe and efficacious product; effects might vary between species, and it's imperative to optimise the amount of ingredients to be dispensed.

There is a growing body of evidence for various positive effects of natural astaxanthin on pets' health, many of which show a similar pattern to humans. For instance, astaxanthin can support canine mobility, endurance, and muscle recovery; the cardiovascular system; cognitive function; attentiveness and at the cellular level, the mitochondria.2–5 Moreover, natural astaxanthin supplementation in dogs and cats could enhance their innate defence systems and improve both their cell-mediated and humoral immune responses.6,7 Astaxanthin also has shown potential to improve impaired vision due to age-related conditions like cloudy lenses in dogs.8 

'The recorded health effects may seem quite diverse; however, they are all rooted in astaxanthin's unique molecular structure. Due to its linear, polar-nonpolar-polar molecular layout, natural astaxanthin can effectively penetrate and traverse the cell and mitochondria membranes and neutralize reactive oxygen species (ROS) in both the hydrophobic interior and hydrophilic exterior boundaries. In addition to providing better protection to the cells and their powerhouses against oxidative stress, natural astaxanthin also has anti-inflammatory effects that support multiple bodily organs and systems.' -  Behnaz Shakersain, Scientific Affairs Manager at AstaReal.
Scoring with Natural Astaxanthin Options
As neither humans nor animals can produce astaxanthin in their bodies, they can only benefit from its protective functions through nutritional intake. To obtain effective amounts, dogs are generally recommended to be fed 1 mg of astaxanthin per 10 kg body weight, which equates to about two wild King salmon fillets for a beagle or three for a golden retriever per day. Feed or treats rich in astaxanthin might offer an easier and more sustainable solution in many cases. 

Natural algae-derived versions of astaxanthin offer additional advantages, such as higher levels of antioxidant potency. Moreover, algae play an essential role in the planet's ecosystem, and being recognised as a renewable resource resonates strongly with responsible consumers. If algae are cultivated indoors, they can be better protected from environmental harm or contamination, and the yield of astaxanthin-rich algal biomass has a higher quality profile. 

Developing a formula with healthy ingredients is only the first step, according to Peter Ahlm: 'Pet food manufacturers also need to make sure that their product will remain stable and nutritious throughout its intended shelf-life. Bioactive substances are particularly prone to interact with other compounds in multi-ingredient formulations or can degrade during harsh production processes, such as extrusion or pelleting.' 

To minimize such risks and protect the power of astaxanthin, AstaReal uses encapsulation in its animal nutrition brand NOVASTA®. Its recently launched NOVASTA® EB15 can be mixed into pet food or added to supplements and consists of algal flour (32%) encapsulated in rapeseed oil with a final astaxanthin concentration of 1.5%. Due to encapsulation, it can be better incorporated into challenging formulations, such as pellets, meal mixes, and soft chews, which are more likely to be exposed to air at ambient temperature.

If manufacturers are sensitive to the shifting demands of pet parents and are willing to combine health with sustainability trends, they are well set. Algal astaxanthin can play an assisting role in these efforts. Thanks to its antioxidant and multifunctional effects, it naturally supports the well-being of our four-legged friends while stemming from a futureproof source.
Futureproof Feeding
One of today's major challenges is how to feed the planet sustainably. In search of plant-based sources for both human and animals, algae are gaining attention. Algae are relatively easy to cultivate, are nutritious, and being considered as more sustainable than several conventional crops. One precious and health-promoting ingredient that algae offer is astaxanthin. AstaReal derives the carotenoid from the micoralgae Haematococcus pluvialis that are being cultivated indoor in specially designed photobioreactors. The company applies a unique system to reuse the excess heat produced during the algae cultivation process to heat up 2500 apartments in the nearby residential area, aiming to continuously reduce their carbon footprint.   By AstaReal

Unlock Innovative Possibilities in Wet Pet Food Formulation with the Power of Faba Bean Protein

Demand for wet pet food is on the rise, with the segment's growth being driven by pet owners looking for premium and nutritionally balanced pet food with good palatability.i At the same time, consumers increasingly want to see more plant-based offerings that also reflect their own sustainability values. In response to these evolving expectations, BENEO has conducted a new set of technical trials to explore the potential of its faba bean protein concentrate as a functional, plant-based ingredient for wet pet food.
Exploring Alternatives to Animal Blood Plasma
In premium and super-premium wet pet food, maintaining consistent product quality is essential. These products typically contain at least 50 wt% total moisture, and their quality is standardised and maintained through the addition of spray-dried animal blood plasma (ABP). This ingredient provides excellent texturizing and emulsifying properties but can come at a high cost. Moreover, due to its animal origin, ABP is increasingly perceived as undesirable by consumers who increasingly want more plant-based ingredient options for their pets.
  To address these challenges, BENEO initiated a series of technical trials in collaboration with Passion4Food, a specialist service provider for the pet food industry. The objective was to evaluate whether faba bean protein concentrate could be used as a suitable and cost-effective alternative to ABP in wet pet food formulations.
Technical Trials Confirm Strong Functional Performance
The initial trials investigated the performance of BENEO's faba bean protein concentrate when partially (50%) or fully (100%) replacing ABP in high-protein wet pet food loaves (paté format). The results showed that the ingredient could be successfully used for both full and partial ABP replacement, with no significant change in the end product's weight or texture. This means producers can maintain desired product quality while achieving considerable cost savings compared to ABP. Based on these promising results, BENEO carried out follow-up trials using a test recipe suitable for commercial scalability.  

As part of the following additional trials, the same percentages of ABP and faba bean protein concentrate were used and compared to a test recipe in which ABP was partially replaced at 50% with pea protein concentrate.
  The data demonstrated that BENEO's faba bean protein concentrate acted as an excellent and cost-effective alternative binder to ABP, with no significant changes observed in loaf height, weight, hardness, or adhesiveness. In contrast, the partial replacement of ABP with pea protein concentrate led to a significant decrease in hardness, indicating that faba bean protein concentrate provides a higher binding capacity in wet pet food loaves. This makes it a valuable ingredient for maintaining the desired texture of the end-product while reducing reliance on animal-derived binders.  
Patent Application Supports Scientific Innovation
Following these successful results, BENEO filed an international patent application for the use of faba bean protein concentrate as an alternative to spray-dried animal blood plasma in wet pet food. The patent application was published in August 2025, underscoring BENEO's dedication to research-based innovation and functional ingredient development for the pet food industry.
Nutritional and Formulation Advantages
Beyond its technical and cost benefits, BENEO's faba bean protein concentrate also provides strong nutritional value. With a protein content of 61 g per 100 g on a dry matter basis and an ileal digestibility score of almost 90%, it is a highly digestible source of protein. Its amino acid profile is relatively rich in lysine and can complement cereal proteins, such as rice protein or vital wheat gluten, to achieve a complete essential amino acids profile.

The ingredient also provides flexibility for product positioning. It is listed in the EU Catalogue of Feed Materialsii and can be used in formulations that carry 'no grain' claims.
Contributing to Sustainable and Locally Sourced Solutions
Sustainability has become an increasingly important consideration for both consumers and producers. BENEO's faba bean protein concentrate offers strong sustainability credentials linked to the faba bean crop and to BENEO's local sourcing and production processes in Germany. Local production in the new state-of-the-art pulse-processing plant, located in Obrigheim, further supports short transport distances, secures supply and reduces the environmental impact compared to more resource-intensive ingredients.
  Dr Maygane Ronsmans, Product Manager Animal Nutrition at BENEO, comments:

'With two in three pet owners considering plant-based proteins to be better for the environmentiii, demand has grown for sustainable and locally sourced vegetal protein ingredients. As the technical trials show, BENEO's faba bean protein concentrate offers pet food manufacturers a win-win scenario: producers can decrease their recipe costs while benefitting from secure supply and meeting consumer expectations for more sustainable and plant-based pet foods, without impacting the quality of the end-product.'
Supporting the Next Generation of Wet Pet Food Innovation
The findings from BENEO's trials confirm that faba bean protein concentrate combines functionality, nutritional quality and sustainability. It performs effectively as a binder in wet pet food, delivers a high level of digestible protein, and provides a viable alternative to animal blood plasma in applications where consistency and texture are key.
  For pet food manufacturers, this opens the door to new formulation strategies that balance technical performance, cost efficiency and environmental responsibility. As the market continues to evolve, ingredients such as BENEO's faba bean protein concentrate can help producers meet consumer expectations for more plant-based, locally sourced and high-quality products.
