Uses of Sodium Tripolyphosphate STPP CAS 07758-29-4:
With the capability of maintaining water, the primary uses of food grade sodium tripolyphosphate are to improve the eating quality in food processing, especially in meat and fish products. 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.
It may also be used as a food starch modifier.
With the functions of chelating metal ions, suspending, dispersing, emulsifying, pH buffering, and etc, technical grade STPP is widely used in the production of laundry detergents & dishwashing detergents, industrial water softener, industrial cleaner, a grease remover, leather pre-tanning agent, dyeing auxiliary agent and so on.
