Food Grade Sodium Tripolyphosphate Application

Food grade sodium tripolyphosphate (STPP) can improve the taste and texture of food. Sodium tripolyphosphate can make food more delicate and soft, and can prevent protein condensation in food, maintaining its natural taste and texture.
Food grade sodium tripolyphosphate (STPP) can be used as a water retaining agent and preservative. Sodium tripolyphosphate can combine with metal ions such as protein, calcium, and magnesium in food to form soluble complexes, thereby reducing the hardness of the solution and increasing the water retention and freshness of food.
Food grade sodium tripolyphosphate (STPP) can be used as a leavening agent. During food processing, sodium tripolyphosphate can generate gas, which increases the volume and softness of food. For example, when making baked goods such as cakes and cookies, adding an appropriate amount of sodium tripolyphosphate can improve the taste and texture of the product.
Food grade sodium tripolyphosphate (STPP) can be used as a coagulant. Sodium tripolyphosphate can coagulate proteins, starch, and other components in food, thereby improving the structure and stability of the food.
Food grade sodium tripolyphosphate (STPP) can serve as a metal chelating agent and pH regulator. Sodium tripolyphosphate can prevent the formation of scale and precipitation, regulate the pH value of food, and improve the stability and texture of food.
