Soy-derived proteins, ranging from the high-volume commodity Soya De Oiled Cake (Soya DOC) to highly refined ingredients like Soy Protein Isolate (SPI) & Soy Protein Hydrolysate (SPH) are a universally significant, plant-based protein source originating from the Glycine max soybean. These products represent a processing value chain starting with solvent extraction of defatted meal (DOC, an animal feed staple at 44-48% protein), which is further processed through aqueous extraction, precipitation, and purification to yield human-grade SPI (minimum 90% protein). Advanced enzymatic hydrolysis converts SPI into SPH (CAS 68607-88-5), a form with improved digestibility suitable for medical and infant nutrition. While Soya DOC is traded globally as an agricultural commodity (HS 2304.00), SPI (CAS 9010-10-0) is a versatile functional ingredient highly valued in the functional food sectors for its emulsification properties, excellent amino acid profile, and role as the foundation for modern plant-based meat alternatives and nutritional supplements. The versatility of these soy fractions provides a sustainable protein solution across the food, feed, and nutraceutical industries globally. We are the leading various Soy-derived proteins supplier worldwide, ensuring comprehensive regulatory support & CoA traceability for various grades with global supply capability with reliable lead time.

Chemical Properties & Specifications
High Degree of Hydrolysis (DH) often results in a pronounced bitter taste due to exposed hydrophobic peptides, requiring careful formulation (masking agents) for consumer acceptance
Although safer than intact protein, rapid ingestion of highly concentrated free amino acids/peptides can sometimes lead to transient gastrointestinal discomfort (osmotic effect)
Enhanced bioavailability and reduced allergenicity are required
Formulas for individuals with GI distress or malabsorption
Peptides (low molecular weight) are less antigenic than intact proteins
Rapid absorption post-exercise due to high concentration of di- and tri-peptides
Used for its savory (Umami) profile in meat analogs, broths, and seasonings.
Store in a hermetically sealed container under low humidity conditions (RH ≤ 50% is highly recommended) and controlled temperature
Highly hydroscopic (moisture-absorbing), which leads to accelerated clumping, reduced flowability, and can encourage non-enzymatic browning (Maillard reaction) over time, degrading quality.
