Mainly used in food and industrial industries.

Among them, the food industry applications are mainly:

· Sodium hmetaphosphate is used in meat products, fish sausage, ham, etc., which can improve water retention, increase adhesion, and prevent fat oxidation;

· Used in soy sauce and soy sauce to prevent discoloration, increase viscosity, shorten fermentation period and adjust taste;

· Used for fruit drinks and refreshing drinks, which can improve juice yield, increase viscosity and inhibit vitamin C decomposition;

· For ice cream, it can improve the expansion capacity, increase the volume, enhance the emulsification to prevent the damage of the paste, and improve the taste and color;

· For dairy products and beverages to prevent gel precipitation;

· Adding beer can clarify the liquor and prevent turbidity;

· Used for canned beans, fruits and vegetables, can stabilize natural pigments, protect food color;

· Sodium hexametaphosphate aqueous solution sprayed on cured meat can improve anti-corrosion performance.

The industrial sector is mainly:

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

· Sodium hexametaphosphate as a water softener, such as used in dyeing and finishing, plays a role in softening water;

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