Sodium Tripolyphosphate (STPP) Food Grade – Brief Summary:
Sodium Tripolyphosphate (Na5P3O10) is a white, crystalline powder commonly used as a food additive and preservative. In food processing, it acts as a sequestrant, emulsifier, and moisture-retaining agent. It helps improve the texture and water-holding capacity of meats, seafood, and poultry, keeping them tender and juicy after cooking.
STPP also stabilizes proteins and prevents fat oxidation, extending shelf life. It is widely used in processed meats, seafood (like shrimp and fish fillets), dairy products, and baked goods.
Key properties:
Appearance: White granular or powder
