Description OF FOODCHEM STPP Sodium Tripolyste Food Grade Granular
STPP Sodium TripolysteAssay:94%;White powder/granuleType:FOOD Grade,Tech Grade25 KG/BAGSShelf life:2 years
STPP or sodium triste is an inorganic compound with formula Na5P3O10. STPP,Sodium Tripolyste is the sodium salt of the polyste penta-anion, which is the conjugate base of trisric acid. Sodium tripolyste is produced by heating a stoichiometric mixture of disodium ste, Na2HPO4, and monosodium ste, NaH2PO4, under carefully controlled conditions.

Application OF STPP Sodium Tripolyste
In Food:
The uses of stpp include using it as a preservative. Sodium Tripolyste 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 tripolyste stpp , serving the same general purpose as it does in human food.
In Tech:
The majority of STPP Sodium tripolyste is consumed as a component of commercial detergents.
Other uses include "ceramics (increase viscosity of the glazes upto a certain limit), leather tanning (as masking agent and synthetic tanning agent - SYNTAN), anticaking, setting retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation, antifreeze."STPP is used as a polyanion crosslinker in polysaccharide based drug delivery.
