Enzymatic Yeast Hydrolysate｜Easy‑Absorb Small‑Peptide Protein for Aquaculture, Piglets & Pets

Product Introduction

Yeast Hydrolysate is a natural functional fermented protein ingredient produced from brewer's or baker's yeast through controlled autolysis and enzymatic hydrolysis. Unlike intact‑protein ingredients, its core value lies in a distinctive processing approach: by precisely controlling the degree of hydrolysis, large protein molecules are targeted for breakdown into small peptides and free amino acids — nutritional forms that are far more readily absorbed directly by the animal digestive tract — while retaining a rich profile of accompanying bioactive components such as nucleotides, B‑vitamins, and minerals.

This “pre‑digested” processing logic gives Yeast Hydrolysate a natural advantage in diets for young animals whose digestive systems are not yet fully developed — such as weaning piglets and early‑stage fish and shrimp larvae. Its distinctive umami flavor profile also gives the product excellent palatability‑enhancing properties, making it a widely recognized functional ingredient in aquafeed, weaning piglet diets, and premium pet food formulations.

Core Components & Mechanism of Action

• Small Peptides: lower molecular weight allows direct absorption through intestinal small‑peptide transporters, without needing full breakdown into free amino acids, giving significantly higher absorption efficiency than intact protein.

• Free Amino Acids: generated during hydrolysis, absorbed directly into the bloodstream, providing immediately usable amino acid nutrition, especially valuable during weaning, transport, or high‑density stress.

• Nucleotides: important raw materials for DNA/RNA synthesis, supporting rapidly growing young animals and actively proliferating cells such as intestinal epithelial and immune cells, widely recognized for immune‑modulating function.

• B‑Vitamins and Minerals: naturally retained through fermentation and hydrolysis, supporting energy metabolism and enzymatic reactions.

This “small peptides + free amino acids + nucleotides” triad of nutritional components is the scientific foundation that sets Yeast Hydrolysate apart from ordinary yeast powder or intact‑protein ingredients — enabling it to simultaneously deliver high absorbability, strong palatability, and clearly defined functional benefits.

Production Process

1. Strain Fermentation: premium brewer's or baker's yeast is fermented to ensure sufficient accumulation of base cellular nutrients

2. Controlled Autolysis/Enzymatic Hydrolysis: temperature, pH, and hydrolysis time are precisely controlled to target peptide molecular weight distribution, avoiding both under‑ and over‑hydrolysis

3. Membrane Separation & Purification: removes impurities while preserving active nutritional components

4. Low‑Temperature Drying: maximizes retention of heat‑sensitive components such as small peptides and nucleotides

5. Batch Testing: every batch is tested for crude protein and moisture content, ensuring consistent quality

Product Efficacy

• High digestibility and absorption via small peptide and free amino acid nutritional forms

• Excellent palatability from distinctive umami compounds

• Immune function support through nucleotides and related bioactive components

• Stress response mitigation during weaning, regrouping, and high‑density stress scenarios

Applicable Species & Typical Use Cases

Aquaculture: Partially replaces fish meal as a premium protein source; small peptide form suits underdeveloped digestive systems of fish and shrimp larvae; supports immune function amid water quality and density stress.

Weaning Piglet Diets: Small peptides and free amino acids are readily absorbed during the weaning stress period, easing the transition to solid feed.

Pet Food: Natural, clean‑label attributes and excellent palatability make it well‑suited for young pets and sensitive‑digestion formulations.

Poultry and Other Species: Applicable to early‑stage poultry diets and other formulations with specific digestion and absorption needs.

Core Product Advantages

• Superior absorption efficiency versus intact‑protein ingredients

• Outstanding palatability from natural umami compounds

• Clearly defined, evidence‑based functional benefits

• Strong fit for weaning, larval, and other high‑stress scenarios

• Consistent, controlled quality via precise hydrolysis and batch testing

Recommended Usage

Specific inclusion rates should be determined under the guidance of a professional feed nutritionist, based on species, growth stage, and overall diet formulation. Especially recommended for aquaculture larval diets, pre/post‑weaning piglet diets, palatability‑focused pet food formulations, and periods of reduced appetite or weakened digestion.

Frequently Asked Questions

• Q1: What's the difference between Yeast Hydrolysate and ordinary yeast powder?

• Ordinary yeast powder delivers nutrition in intact‑protein form, while Yeast Hydrolysate breaks protein down into small peptides and free amino acids via enzymatic hydrolysis — resulting in higher absorption efficiency and stronger palatability.

• Q2: Can Yeast Hydrolysate fully replace fish meal?

• It is better suited as a partial replacement and functional supplementary ingredient rather than a full replacement. Consult a professional nutritionist for an appropriate substitution ratio.

• Q3: Where does the product's palatability advantage come from?

• Free amino acids and flavor compounds generated during hydrolysis naturally carry umami characteristics, effectively enhancing feed palatability.
