Formula:(NaPO3)6
CAS No.: 10124-56-8
F.W.:611.77
Sodium hexametaphosphate(SHMP) has been used as a good food additive through rigorous test and index determination. For example, canned food is very popular because it can be preserved at room temperature for a long time. It can not only preserve meat and fish, but also preserve fruit food. Food from all over the world is packaged and delivered to other countries to enable people to taste exotic flavors. The Hygienic Standard for the Use of Food Additives (GB 2920-1996) stipulates that it can be used in canned, fruit juice (fruit flavor) beverages and vegetable protein beverages with a maximum usage of 1.0g/kg; aquatic products, dairy products, poultry products, meat products, ice cream, instant noodles with a maximum usage of 5.0g/kg.
For industrial use, such as oil field, paper-making, textile, dyeing, petrochemical industry, tanning industry, metallurgical industry and building material industry, it is mainly used as a water softening agent in solution for printing, dyeing, and boiler; Diffusant in papermaking; slow corrodent, floating agent, dispersing medium, high temperature agglomerant, detergent and soil analytical chemistry reagent.
For food grade, it is mainly used as additive agent,pH adjusting agent and fermentation agent, and nourishment.
