Sodium Hexametaphosphate (SHMP)
Sodium hexametaphosphate, abbreviated as SHMP, CAS NO.is 10124-56-8, is an inorganic compound. Its appearance is white crystalline powder, easily soluble in water. The most commonly used specifications are: SHMP 68%.
Applications:
Sodium hexametaphosphate food grade also has a variety of uses. It can increase the stability and freshness of food, and is used as an antioxidant, acidity regulator, acidifier and emulsifier in ham, beverages, ice cream, dairy products, canned fruits and vegetables, etc. In food processing, sodium hexametaphosphate can also be used as a dough conditioner to improve the texture of pastries and extend their shelf life.
Sodium hexametaphosphate SHMP is also widely used in the water treatment industry to prevent scale and corrosion problems. It forms insoluble salts with calcium and magnesium ions in the water, thereby reducing the hardness of the water and preventing the formation of scale. It is also widely used as a chelating agent and metal preservative for the protection and rust prevention of metal surfaces. In addition, it can also be used in dyes and catalysts.
