3. Food Grade Sodium Tripolyphosphate Application
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
4. The advantages of food grade sodium tripolyphosphate
1. Safe and reliable
Food grade sodium tripolyphosphate has undergone strict food safety testing and certification, meets national food safety standards, and can be safely used in food processing. At the same time, it can effectively reduce the heavy metal content in food and improve food safety.
2. Significant effect
Food grade sodium tripolyphosphate has significant effects in improving food quality, taste, and structure. It can effectively improve the water retention of food, prevent food cracking, improve the organizational structure of food, and make food more delicious and delicious.
3. Wide applicability
Food grade sodium tripolyphosphate is suitable for the processing and storage of various foods, such as meat, fish, beans, baked goods, etc. It can be used alone or in combination with other additives to meet the needs of different food processing.
