Application situation

1. Mainly used in food and industrial industries. Among them, the food industry applications are mainly:

Sodium hexametaphosphate is used in meat products, fish sausages, ham, etc., can improve water holding capacity, increase adhesion, and prevent fat oxidation;

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

Used in fruit drinks and refreshing drinks, it can increase the juice yield, increase the viscosity, and inhibit the decomposition of vitamin C;

Used for ice cream, it can increase the expansion capacity, increase the volume, enhance the emulsification to prevent the destruction of the paste, and improve the taste and color;

Used in dairy products and beverages to prevent gel precipitation;

Adding to beer can clarify the liquor and prevent turbidity;

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

The aqueous solution of sodium hexametaphosphate is sprayed on the cured meat to improve the corrosion resistance.

2. The main industrial sectors are:

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

Sodium hexametaphosphate is used as a water softener, if it is used in dyeing and finishing, it has a soft water effect;

Sodium hexametaphosphate is also widely used as a scale inhibitor in water treatment industries such as EDI (Resin Electrodialysis), RO (Reverse Osmosis), NF (Nanofiltration), etc.
