Sodium triphosphate (STP), E451i also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP),) is an inorganic compound with formula Na5P3O10. Though it’s considered safe, some are convinced it has potentially dangerous health effects.
What Is Sodium Tripolyphosphate E451i?
Sodium Tripolyphosphate (STPP) E451i is a white water soluble powder that is the sodium salt of the polyphosphate penta-anion. Sodium Tripolyphosphate (STPP) is used in the food and beverage industry as a preservative and as an emulsifier. Specifically, Sodium Tripolyphosphate (STPP) is used in seafood, meats, and poultry.
Possible Side Effects of Sodium Tripolyphosphate E451i
Though Sodium Tripolyphosphate E451i is regarded as safe supplement, there maybe some side effects:
GRAS Affirmation: Yes
Generally recognized as safe (GRAS) is an American Food and Drug Administration (FDA) designation that a chemical or substance added to food is considered safe by experts, and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements. Sodium Tripolyphosphate is considered safe.
Suggested Dosage
