Soy Peptide Powder is a food-grade enzymatic hydrolysate of soy protein delivering low-molecular-weight peptides (<3000 Da) with improved solubility, rapid absorption, reduced allergenicity, and bioactive properties (antioxidant, ACE-inhibitory) for sports, clinical, and functional nutrition.We supply bulk Soy Peptide Powder sourced from leading China manufacturers, available in powder form for food and beverage manufacturers worldwide. Our Soy Peptide Powder is widely used in sports recovery supplements, elemental nutrition, drink mixes, medical foods and weight-management formulations. HS Code: 35040090
Soy Peptide Powder is produced by controlled enzymatic hydrolysis of soy protein isolate using food-grade proteases, followed by filtration, decolourisation, desalting, concentration and spray drying.
The resulting small peptides offer superior solubility across pH, rapid amino acid delivery, reduced antigenicity, and bioactive benefits for performance and health applications.
