About Soy Protein Isolate (SPI)

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 processin...

Protein Content

Min 90% (dry basis)

Functional Hydrocolloid & Allergen Hazard (Critical)

Major food allergen. Strict GMP cross-contamination prevention (HACCP/GMP) and mandated labeling are required in all human food/supplement applications

Handling

Fine, dry powder requires proper ventilation to prevent inhalation, which may cause respiratory irritation

Nutritional Fortifier (> 90% Protein)

Superior functional properties

Emulsification/Fat-Binding

Stabilizes fat/water emulsions in processed meats and dressings

Gelation/Structure

Forms heat-set gels for creating meat analogues (Tofu/TVP) and providing texture

Viscosity

Nutritional beverages and supplements to control mouthfeel and suspension

Preservation of Functional Properties (PDI)

Store in a sealed, airtight container/bag in a cool, dry place (ideally < 25°C and < 60% Relative Humidity)

Detail 2

Exposure to moisture causes clumping (caking), can irreversibly reduce the Protein Dispersibility Index (PDI), compromising solubility and functional performance
