Usage: Mainly used in meat foods, meat cans and other food industries as quality improver.
Sodium tripolyphosphate/STPP food grade is used as water retaining agent, softening and tenderizing agent. It can enhance protein and globulin, so it can increase the hydration and water retention of meat products, improve the water permeability, promote the softening of food, improve the quality of food, and maintain the good flavor of food.
