3. Food Grade Sodium Tripolyphosphate Application
Sodium Tripolyphosphate (STPP) is a commonly used phosphate compound with various functions and applications.
Food industry: Sodium tripolyphosphate, as a food additive, is mainly used in the processing of meat products, aquatic products, and dairy products to improve water retention, freshness, and texture. It can combine with proteins to form stable complexes, increase the water retention of food, prevent food dehydration and texture hardening. In addition, sodium tripolyphosphate can also regulate the pH value of food, improve its stability and texture.
Cleaning agents and detergents: Sodium tripolyphosphate has good chelating and dispersing properties, can bind with metal ions, and prevent the formation of scale and precipitation. Therefore, it is often used as a chelating and dispersing agent in detergents and cleaning agents, for removing stains, cleaning, and removing scale.
Industrial use: Sodium tripolyphosphate is also widely used in industrial fields, such as water treatment, textiles, papermaking, ceramics, etc. It can combine with metal ions such as calcium and magnesium to prevent the formation of scale and precipitation, and protect the normal operation of equipment and pipelines.
It should be noted that the use of sodium tripolyphosphate should follow corresponding regulations and standards, and the dosage should be reasonably controlled to ensure safety and compliance.
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.
