Q: What is Sodium Tripolyphosphate?
A: 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.
Q: How do you produce it?
A: Sodium tripolyphosphate is produced by heating a stoichiometric
mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully
controlled conditions.
Q: Sodium Tripolyphosphate Food Grade Usage?
A: 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.
STPP sodium tripolyphosphate also has been used in helping to preserve the quality of drinks such as
milk and fruit juices.
