Sodium Tripolyphosphate (STPP), also known as Sodium Triphosphate or Pentasodium Tripolyphosphate, is a food-grade compound widely used in industrial, commercial, and food applications.

In food production, STPP is used as a preservative for seafood, meats, and poultry, retaining moisture and improving texture. It is listed as E number E451 and approved by the FDA as "generally recognized as safe." Beyond food uses, it functions as an emulsifier, sequestering agent, and deflocculating agent in ceramics and soaps.
