Application Trend of Hydrolyzed Yeast in Pet Food

The pet food industry is experiencing rapid development and, at the same time, there is a growing need to focus on protein sources that do not compete with human food. It is important to effectively utilize resources while minimizing environmental pollution and habitat loss. The global demand for both plant and animal proteins, both in terms of per capita and annual consumption, is significantly increasing. Hydrolyzed yeast, with its natural, low-carbon, and allergen-free product attributes, can be added to all categories of pet food, making it a novel functional protein ingredient. Moreover, hydrolyzed yeasts contain abundant flavoring compounds which give them unique flavors. These compounds can improve the intestinal health of pets and effectively enhance their palatability, specifically in dogs and cats.

What is Hydrolyzed Yeast?

The production of fresh yeast results in carbon emissions that are only one twentieth of those produced by beef production, making it environmentally friendly. Hydrolyzed yeast is a product obtained through extensive processing of yeast, which is rich in proteins, nucleic acids, B vitamins, and other nutrients. This process involves using natural highly active yeast strains, conducting deep liquid fermentation, and employing both endogenous enzymes (intracellular autolytic enzymes) and exogenous enzymes for targeted hydrolysis. The resulting product is then concentrated and dried. Through these processing methods, the intracellular substances of yeast cells are fully released, maximizing the functionality of their properties. Hence, hydrolyzed yeast is packed with nucleotides, nutritional small peptides, digestive enzymes, abundant B vitamins, and also contains a certain amount of cell wall polysaccharides, making it a novel functional protein ingredient.

Improving Pet Immune Health

Hydrolyzed yeast contains abundant nucleic acids, mannan oligosaccharides, glucans, and other components. Research has shown that infants who consume fortified nucleotide milk powder exhibit better immune responses, as it enhances humoral immune responses and increases cytokine production. Results from in vivo experiments, where nucleotides were added to the diets of rats, yielded similar findings. Nucleotides are considered semi-essential nutrients and have been found to improve the replication of DNA and the synthesis of RNA in rapidly dividing tissues. Since nucleotides serve as the building blocks for RNA synthesis, the regeneration of new tissues is accelerated after injury or during nutrient deficiencies.

Hydrolyzed yeast typically contains nucleic acid concentrations ranging from 6% to 10%, making it a valuable source of nucleic acids and nucleotide-like substances for pets. As a genetic material of life, nucleic acids play a role in promoting intestinal development and mediating improved immune responses in pets. Studies on human infant formula have indicated that adding nucleic acid substances has significant implications for enhancing pet immune health.

Enhancing Pet Palatability

Yeast-derived products enrich the flavors of pet food, bringing out savory, sweet, and other taste profiles, resulting in a more long-lasting flavor experience. Hydrolyzed yeast, being a natural food ingredient, has gained significant popularity in the development of modern pet food. Besides its natural origin, it also possesses organic certification, ensuring sustainability and availability.

Improving Pet Intestinal Health

During the juvenile stage, dogs and cats have developing intestines with incomplete digestive function. Research conducted between 2019 and 2021 indicates that approximately half of dogs and cats experience suboptimal health or health issues. Among them, 24.3% of dogs and 25.4% of cats face intestinal health problems, making digestive system health the primary concern for pets. This is due to the vulnerability of pets' intestinal villi during this period, which affects the absorption of nutrients from their diet. Moreover, the imbalance of intestinal microbiota can lead to diarrhea and compromised immune performance. Consequently, the promotion of pet digestive health has become a focal point in pet food research.

Nutritional research findings have shown that the injection of nucleotides and the addition of nucleotides to infant formula can improve the intestinal health and immune system development in infants and young children. Nucleotides and small peptides play a role in maintaining intestinal health, which is why yeast-derived nucleic acid nutrition is incorporated into pet food for young dogs and cats. This addition effectively improves the overall diet structure and promotes the intestinal health of young pets. Furthermore, the inclusion of hydrolyzed yeast in pet cat food helps to enhance the balance of gut microbiota. The Beijing Academy of Agricultural Sciences conducted a study specifically on hydrolyzed yeast in pets, which revealed that the group receiving hydrolyzed yeast displayed increased Bifidobacteria abundance compared to the control group. Additionally, the hydrolyzed yeast group exhibited higher levels of Lactobacillus abundance than the control group and other treatment groups. These findings indicate that the inclusion of hydrolyzed yeast yields superior results in improving the intestinal health of pet cats in comparison to other treatment approaches.

In addition, to investigate the effects of adding hydrolyzed yeast, the study examined the impact on the content of indole and skatole in pet cat feces. The results demonstrated that the inclusion of hydrolyzed yeast significantly reduced the levels of skatole, indole, and other harmful substances in the feces. This addition effectively increased the content of bifidobacteria in pet feces and improved their intestinal health.

GroPro - the hydrolyzed yeast by Angel, represents a cutting-edge microbial protein resource that provides numerous advantages. Its formulation is enriched with flavor substances and distinctive tastes, ensuring high palatability for both dogs and cats. The hydrolyzed yeast contains a diverse range of special nutrients, such as yeast nucleic acid, nucleotides, yeast peptides, and other unidentified substances, all of which contribute to its exceptional nutritional value. As a result, hydrolyzed yeast finds extensive applications in the pet food industry, including puppy and cat food, prescription diets, pet snacks, and wet food. With its remarkable attributes and versatility, GroPro is poised to make a significant impact in the ever-growing pet food market.
