DESCRIÇÃO

Sodium tripolyphosphate (STP, sometimes STPP or sodium triphosphate or TPP) is an inorganic compound with formula Na5P3O10. Sodium triphosphate is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triPhosphoric Acid.Sodium tripolyphosphate is produced by heating a stoichiometric mixture of Disodium phosphate, Na2HPO4, and Monosodium Phosphate, NaH2PO4, under carefully controlled conditions.

The uses of Sodium tripolyphosphate also include using it as a preservative. Sodium Tripolyphosphate STPP can be used to preserve foods such as red meats, poultry, and seafood, helping them to retain their tenderness and moisture. Pet food and animal feed have been known to be treated with sodium triphosphate, serving the same general purpose as it does in human food.
