Sodium Tripolyphosphate (STPP), also called pentasodium triphosphate, is a white, free-flowing food phosphate (E451(i)). In food processing it works as a sequestrant and emulsifying salt: it binds calcium and magnesium, holds water in protein, and keeps texture stable through freezing and cooking.
The largest food use is moisture retention in seafood, shrimp, meat and poultry. It is also used in processed cheese, dairy products, noodles and flour products. We manufacture food grade STPP in-house at our FSSC 22000 certified Bawana plant and supply it across India and to export markets, with COA, TDS and SDS for every batch.
