Sodium Tripolyphosphate STPP

Food additives
The uses of STPP also include using it as a preservative. It 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 STPP,
serving the same general purpose as it does in human food. STPP also has been used in helping to preserve the quality of drinks
such as milk and fruit juices.
