Description
Sodium tripolyphosphate (abbreviated as STP; sometimes referred to as STPP, sodium triphosphate, or TPP) represents an inorganic compound with the chemical formula Na5P3O10. Sodium triphosphate is the sodium salt of the polyphosphate penta - anion, and this penta - anion is the conjugate base of triPhosphoric Acid. The production of sodium tripolyphosphate involves heating a stoichiometric blend of Disodium phosphate (Na2HPO4) and Monosodium Phosphate (NaH2PO4) under precisely controlled circumstances.
Applications
One of the applications of sodium tripolyphosphate is its use as a preservative. Sodium Tripolyphosphate (STPP) can be applied to preserve various foods like red meats, poultry, and seafood. It plays a role in maintaining their tenderness and moisture content. Moreover, it is well-known that sodium triphosphate is used in pet food and animal feed, fulfilling a similar function as it does in food for human consumption.
