Sodium hexametaphosphate is an inorganic compound with the chemical formula (NaPO3)6. It is a white crystalline powder, easily soluble in water and insoluble in organic solvents. It is mainly used as a quality improver, pH regulator, metal ion chelator, adhesive and expander in the food industry.

PRODUCT APPLICATION

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

(1) Sodium hexametaphosphate is used in meat products, fish sausages, ham, etc. to improve water retention, increase adhesion, and prevent fat oxidation;

(2) It is used in bean paste and soy sauce to prevent discoloration, increase viscosity, shorten the fermentation period, and adjust the taste;

(3) It is used in fruit drinks and refreshing drinks to increase juice yield, increase viscosity, and inhibit the decomposition of vitamin C;

(4) It is used in ice cream to improve expansion capacity, increase volume, enhance emulsification to prevent paste damage, and improve taste and color;

(5) It is used in dairy products and beverages to prevent gel precipitation;

(6) Adding it to beer can clarify the wine and prevent turbidity;

(7) It is used in beans and canned fruits and vegetables to stabilize natural pigments and protect food color;

(8) Sodium hexametaphosphate aqueous solution is sprayed on pickled meat to improve antiseptic properties. 2. The main industrial sectors are:

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

(2) Sodium hexametaphosphate is used as a water softener, such as in dyeing and finishing, to soften water;

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