Sodium Tripolyphosphate (STPP), Powder, Food Grade, Kosher
Sodium Tripolyphosphate (STPP), also known as Sodium Triphosphate, is a food-grade, kosher powder widely used as a water softener, emulsifier, and preservative. It is an essential component in detergents, where it acts as a builder by preventing calcium and magnesium ions from interfering with detergents in hard water. In food production, it is known as E451 and is used to retain moisture in seafood, meats, and poultry. STPP is considered "generally recognized as safe" (GRAS) by the FDA.
