1. Mainly used in food industry applications:
(1) Sodium hexametaphosphate is used in meat products, fish sausages, ham, etc., to improve water holding capacity, increase binding properties, and prevent fat oxidation;
(2) When used in bean paste and soy sauce, it can prevent discoloration, increase viscosity, shorten the fermentation period, and adjust the taste;
(3) Used in fruit drinks and refreshing drinks, it can increase the juice yield, increase the viscosity, and inhibit the decomposition of vitamin C;
(4) Used in ice cream, it can improve expansion capacity, increase volume, enhance emulsification, prevent paste damage, and improve taste and color;
(5) Used in dairy products and beverages to prevent gel precipitation;
(6) Adding it to beer can clarify the liquor and prevent turbidity;
(7) Used in canned beans, fruits and vegetables to stabilize natural pigments and protect food color;
(8) Sodium hexametaphosphate aqueous solution sprayed on cured meat can improve the preservative performance.
2. The industrial industries mainly include:
(1) Sodium hexametaphosphate can be heated with sodium fluoride to produce sodium monofluorophosphate, which is an important industrial raw material;
(2) As a water softener, sodium hexametaphosphate can soften water if used in dyeing and finishing;
(3) Sodium hexametaphosphate is also widely used as a scale inhibitor in EDI (resin electrodialysis), RO (reverse osmosis), NF (nanofiltration) and other water treatment industries.
