Yeast Protein Extract, also called Hydrolyzed Yeast Protein, is a high-quality protein ingredient derived from Saccharomyces cerevisiae. It offers rich amino acids, savory flavor, and excellent digestibility, making it ideal for food, nutraceuticals, and animal feed. We source premium yeast and use enzymatic hydrolysis for optimal solubility and functionality. Available in light yellow to pale brown powder, it has a mild aroma and umami taste. Applications range from flavor enhancers in food (1%-3%) to protein supplements in feed (2%-5%). Our extract stands out for purity, customizable specs, and consistent performance.
