Can Sodium Tripolyphosphate Be Eaten

Sodium tripolyphosphate can be used in food. If the content of sodium tripolyphosphate in food meets the national standard, it can be eaten. Sodium tripolyphosphate can also be added to washing products.

In industry, sodium tripolyphosphate can be used as detergent additive, petroleum, metallurgy, mining, papermaking, water treatment, etc. It is mainly used as the assistant of synthetic detergent, synergist of soap and preventing grease precipitation and frosting of bar soap. It has strong emulsifying effect on lubricating oil and fat, and can be used to adjust pH value of buffer soap.

Due to the introduction of the national phosphorus limitation policy, the application of sodium tripolyphosphate in detergent additives is gradually reduced, and is gradually replaced by layered sodium silicate, molecular sieve and other products.

In food industry, sodium tripolyphosphate can be used as water retention agent, quality improver, pH regulator and metal chelator. According to China's hygienic standard for the use of food additives (gb2760-2011), the maximum consumption of canned food, fruit juice (fruit flavor) beverage and vegetable protein beverage is 1.0g/kg; Dairy products, poultry products, meat products, ice cream, instant noodles, the maximum use of 5.0g/kg.
