Sodium Polyphosphate (Sodium Hexametaphosphate, SHMP) is a food-grade versatile long-chain polyphosphate used as a sequestrant, emulsifier, moisture binder and texture improver in a wide range of food products.We supply bulk Sodium Polyphosphate sourced from leading China manufacturers, available in powder and flake forms for food and beverage manufacturers worldwide. Our Sodium Polyphosphate is widely used in processed meats and seafood, processed cheese, beverages, dairy and soy drinks and canned seafood.
Sodium Polyphosphate ((NaPO₃)ₙ, commonly known as Sodium Hexametaphosphate or SHMP) is a glassy, water-soluble polyphosphate with exceptional metal-ion sequestering, dispersing and water-binding capabilities.
It is one of the most widely used food phosphates, applied in processed meats, seafood, dairy, beverages and canned foods for moisture retention, protein stabilisation, emulsification and prevention of struvite crystal formation.
