Application: Mainly used in food and industry. The food industry is mainly used in: 1, six sodium phosphate for meat products, fish sausage, ham and so on, can improve the water holding capacity, increase the sex, prevent fat oxidation; 2, for the miso, soy sauce can prevent discoloration, increase the viscosity, shorten the fermentation period, adjust the taste; 3, for fruit drinks, cool drinks, can increase the juice rate, increase the viscosity, inhibit the decomposition of vitamin C; 4, for ice cream can increase the expansion capacity, increase the volume, enhance the role of emulsion to prevent the destruction of the paste, improve the taste and color; 5, used for dairy products, beverage to prevent gel precipitation; 6, to join the beer can be clarified liquor, to prevent turbidity; 7, used for beans, canned fruits and vegetables, can stabilize the natural pigment, protect the food color; 8, six sodium phosphate solution sprayed on the cured meat, can improve the anti-corrosion properties. Major industrial sectors: 1, six sodium fluoride can be heated with sodium fluoride to produce sodium fluoride, which is an important industrial raw material; 2, six sodium hexametaphosphate as a water softener, such as used in dyeing and finishing, to soft water; 3, six partial sodium phosphate as scale inhibitor widely used in EDI (resin electrodialysis) and RO (reverse osmosis) and NF (nanofiltration) water treatment industry. Consumption: General 0.3-0.5%, dosage of 0.9% in cheese; 0.3% meat; milk powder, milk powder, frozen fish, shrimp 0.5%; condensed milk, beverage 0.2%. Food grade six partial sodium phosphate in trace amounts of heavy metals such as lead and arsenic, arsenic can cause skin depigmentation, coloring, keratinization and carcinogenesis of systemic poisoning; food grade six partial sodium phosphate and certain content of fluoride and low concentration of fluoride will cause chronic poisoning and fluorosis of bone, the bones of calcium resulted in a decrease in bone sclerosis and osteoporosis.
