Baked Biscuits Utilizing Spray Dried Plasma Products

Background Information   Spray dried plasma (SDP) or Cravings (hydrolyzed plasma) are high-protein ingredients utilized in pet food for functional texture properties, enhancing palatability, or supporting overall health.   Study Objective   The study objective was to evaluate how SDP or Cravings inclusion impacts texture and palatability of baked biscuits utilizing wheat gluten.   Experimental Procedure   The study evaluated palatability and texture of baked biscuits utilizing 1% SDP or Cravings to replace wheat gluten in control formula. Palatability testing was conducted with 20 dogs for a 2-day test. Different ingredient sources and processing conditions were used in each study accounting for differences in texture of final product.
  Baked biscuits were made by preparing the dough utilizing a KitchenAid mixer equipped with a dough hook, rolling out by hand to a set depth and size, and then baking to moisture level of less than 10%. Three replicate batches of each formula were completed for analysis per study.
  Texture was measured on a TA.XT Plus utilizing an adjustable bridge with a rounded-end knife probe for a 3-point bend. Baked biscuits of 2 cm × 7 cm were placed over the two-bridge span spaced 2.5 cm apart to measure maximum force to break (hardness), fracturability, and stiffness to determine texture. Five baked biscuits per treatment were analyzed for texture from each replicate batch. Digital calipers were utilized to measure biscuit dimensions and volume.   Proof of Concept: Test Formula
    Results: Texture
 
Results: Palatability
 
Summary
SDP and Cravings can be incorporated into baked biscuits as a processing aide to impact texture depending on ingredient matrix and target, while SDP also improves palatability. Overall, both SDP and Cravings can be an alternative to vital wheat gluten to maintain or enhance product quality.

Beyond Dry Food: Functional Additives in the Pet Food Market

By Erika Stasieniuk

The answer is in the intersection between nutritional science, consumer behavior, and market strategy.    What Do Pet Owners Value?   The increase in pet humanization has transformed pet owners' view about food. Nowadays, they not only look for satiety but also for disease prevention, healthcare, and well-being promotion, which reflects the concern about their own nutrition and health. 
  This behavior shift is confirmed by Hobbs Jr. and Anderson (2024), who studied which healthy properties claims add value to consumers. Pet owners are willing to pay more for certain benefits, according to the authors of a study on nearly 1,600 dry dog foods.
  The statement 'allergy relief' showed a surcharge of up to 22.7%. 'Digestive health' and 'sensible skin' also correlate with more perceived value. Generic terms such as 'vitamins and minerals' or 'dental care' were associated with a lower willingness to pay, indicating that they are perceived as basic attributes rather than differentiators. This data offers a strategic orientation for the industry—clear and specific claims with visible benefits are more valuable and explain premium positioning.   Functional Additives Applications in Canine and Feline Food   Functional statements that go beyond marketing are backed up by proven efficacy ingredients.
  Additives have always been an integral part of formulations from technological and sensorial goals to nutritional and zootechnical purposes. However, its function has shifted: in fact, it has become a strategic tool for differentiation and commercial value.
  Prebiotics, natural antioxidants, essential fatty acids, and others were increasingly added to formulations both for their technical functionality and their commercial appeal. Among them, ingredients with functional effects stand out in gut health, e.g., mannan oligosaccharides (MOS), fructo-oligosaccharides (FOS), and beet pulp.
  According to Singla and Chakkaravarthi (2017), prebiotics such as inulin and FOS are non-digestible fibers serving as substrates for beneficial gut bacteria (Bifidobacterium and Lactobacillus). Classic studies highlight their benefits:
  Balance in gut microbiota (Gibson y Roberfroid, 1995). Better mineral absorption, such as calcium and magnesium (Scholz-Ahrens et al., 2007). Immune response modulation (Lomax and Calder, 2009). Reduction of inflammatory compounds in the colon (Slavin, 2013).
  MOSs are functional carbohydrates extracted from yeast cell walls, mainly from Saccharomyces cerevisiae. These compounds serve as allies in gut health as they prevent pathogenic bacteria from adhering to the mucosa. MOS are in the binding site of epithelial cells to prevent the adhesion of harmful microorganisms, a mechanism known as competitive exclusion. In addition to the protective effect, MOSs stimulate defense cells (macrophages) by exceeding mannose receptors in glycoproteins of the cell surface (Macari and Maiorka, 2000; Strickling et al., 2000).
  Beet pulp is a fermented fiber, rich in soluble and insoluble fiber. It contributes to the balance of gut microbiota, enhances fecal consistency, and improves bowel transit. Moreover, its partial fermentation in the colon generates short-chain fatty acids (SCFAs), such as butyrate, which serve as an energy source for colonocytes and contribute to the intestinal mucosa integrity (Swanson et al., 2002).
  The statements 'enhance digestive health' or 'balance of intestinal flora' are credible when included in ingredient formulations, such as inulin, FOS, MOS, and beet pulp. The connection between functionality and labeling is essential to building confidence and perception of real value.   From the Ingredient to the Positioning in the Market   Brands face the challenge of identifying technical complexity in clear, attractive, and accessible messages. 
  Instead of mentioning 'inulin' in the list of ingredients, it is better: 'natural prebiotic fiber of chicory roots that promotes gut health.'
  This approach trains the consumer and strengthens the legitimacy of the functional statement. Functional ingredients not only must be listed but also must be perceived and valued as differentiators.
  Other relevant examples:
  Omega-3 (fish oil and linseed): Related to dermis health, coat shine, and joint well-being. Vitamin E and selenium: Natural antioxidants that strengthen the immune system. Glucosamine and chondroitin: Usually present in food for senior dogs or big breeds, which support their beneficial effect in joints.   The Pillars of their Commercial Efficacy   Science-based functional ingredients with an effective dose proven by studies. Clarity and transparency in the communication of their benefits. Alignment between their value proposal and price positioning.   Opportunities in a New Scenario   The search for healthier, specific, and functional food is no longer a trend—it is the standard in the pet food market.
  In an increasingly competitive market, brands successfully combining science, formulation, and an effective communication strategy will be better positioned to address a more demanding and informed consumer.
  Prebiotics and other functional additives, when used with technical expertise and purpose, can make dry food a real tool for the health and well-being of dogs and cats. The market is open to brands that offer more than nutrition: those that build trust.
  Ideal labeling goes beyond attractive promises. It must convince consumers by presenting a science-aligned list of ingredients that support each statement. By bridging the gap between formulation and transparent communication, the industry evolves in promoting a longer and healthier life for pets.

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.
