Sodium hexametaphosphate is an inorganic compound with the chemical formula (NaPO3)6, a white crystalline powder, easily soluble in water, insoluble in organic solvents, mainly used in the food industry as a quality improver, pH adjusting agent, metal ion chelating agent, binder and swelling agent.

Basic information

Main applications

1, mainly used in food and industrial industries. The main applications in the food industry are:

(1) sodium hmetaphosphate used in meat products, fish sausage, ham, etc., can improve water retention, increase adhesion, prevent fat oxidation;

(2) For bean sauce, soy sauce can prevent discoloration, increase viscosity, shorten fermentation period, adjust the taste;

(3) Used in fruit drinks, cool drinks, can improve juice yield, increase viscosity, inhibit the decomposition of vitamin C;

(4) Used for ice cream can improve the expansion capacity, increase the volume, enhance the emulsification to prevent paste damage, improve taste and color;

(5) for dairy products and beverages to prevent gel precipitation;

(6) Adding beer can clarify liquor and prevent turbidity;

(7) Used for canned beans, fruits and vegetables, can stabilize the natural pigment, protect the color of food;

(8) odium hexametaphosphate aqueous solution sprayed on cured meat can improve the anticorrosion performance.

2. The main aspects of industry are:

(1) Sodium hexametaphosphate can be heated with sodium fluoride to produce sodium monofluorophosphate, which is an important industrial raw material;

(2) sodium hexametaphosphate as a water softener, such as used in dyeing and finishing, play the role of water softener;

(3) Sodium hexametaphosphate is also widely used as scale inhibitor in EDI (resin electrodialysis), RO (reverse osmosis), NF (nanofiltration) and other water treatment industries.
