Description

Soy Peptide Powder is a next-generation bioactive nutritional ingredient derived from non-GMO soy isolate protein. Using advanced composite enzymatic directional hydrolysis and precision small-peptide separation technology, the soy protein is broken down into highly absorbable oligopeptides composed mainly of 2–6 amino acids, with molecular weights between 200–800 Da. This small molecular size offers unique physiological advantages, enhanced bioavailability, and superior functional performance in food and health formulations.

Compared with conventional soy protein—which requires extensive gastrointestinal digestion—Soy Peptide Powder can be directly absorbed through the small intestine, providing efficient nutrient delivery regardless of digestive health or age-related digestive limitations. Its excellent solubility across pH 2–10 and outstanding thermal stability allow broad application across liquid beverages, powders, medical formulations, and processed foods.

As a plant-based peptide source containing all essential amino acids and a rich variety of bioactive peptide sequences, Soy Peptide Powder has become a highly desirable ingredient for nutrition brands, sports supplement manufacturers, functional food developers, and pharmaceutical companies.
