1 as quality improver, improve food complexing metal ions, pH, ionic strength increased role, thereby improving food and water holding capacity knot efforts. Chinese regulations can be used for cheese, maximum use of 5g/kg; in ham, meat, fish, shrimp and crab in the maximum usage is 3.0g/kg; Maximum amount of canned food, fruit juice, soft drinks and dairy products to 0.5g / kg.

2, is used in the chemical, textile, printing and dyeing, paper, power generation and other industries in soft water and detergent, boiler scale inhibitor, paper dyed in soft water, pH buffering agents produce glossy paper with adhesive, when printing fixing agent, mercerized fabric enhancer-line anti-brittle agent. Metallurgical industry as a chemical degreasing, decontamination, used as a photographic developing solution excellent accelerator. Bottle tooth cleaners and detergents. Rubber latex coagulant. Juice purification agent. Phosphate from quality improvement role in food processing, for example, keep the water holding capacity of meat, such as efforts to enhance the role of the junction in order to reduce the loss of nutrients in meat and meat tenderizer preservation of the meat products. In food processing is also used as an emulsifier, nutritional supplements, quality improver. Food preparation surface is alkaline materials, also used in the manufacture of refined sugar and α-starch. Also used as a food bottles, cans and other detergents. [3]
3, solid trisodium phosphate (TSP) are weak alkali salts, with a strong alkaline and high solubility, chemically stable, long-term preservation, the containment spray system (EAS) spray water added TSP substitute NaOH, able to adjust the pH of the spray solution, effectively removing the release of cooling water to leak from the containment iodine gas to avoid alkali injury to staff, easy to clean up after the accident.
