Sodium Tripolyphosphate (STPP) it’s a sodium salt of the polyphosphate penta-anion, also known as Penta sodium tripolyphosphate, which is a preservative for seafood, meats, poultry, and animal feeds.

It’s used in food processing, especially in meat and fish products to reduce the amount of thaw water (or maintain water) and make seafood look firmer and smoother because of the capability of maintaining water. It may also be used as a food starch modifier.

It is also applied in pet food (e.g. cat and dog food) for the purpose of binding water and keeping the animal feed fresh. STPP is an active ingredient that binds calcium in the saliva to help reduce tartar formation and promote dental health. 80% of dogs and 70% of cats aged over 3 years have some form of gum disease, this easily-digestible ingredient can also help prevent teeth stains and stop plaque buildup on teeth, which is the better way to contribute pet dental health.
