1.Sodium Trimetaphosphate(STMP)
Molecular formula: Na3O9P3
CAS Number: 7785-84-4
HS Code: 2835299000
1.Properties
White crystal powder, relative density at 2.54g/cm3, easily soluble in water, but not in alcohol.
2.Application
As a starch improver apply for flour, pastry products, etc.;
In the food industry, it is used as starch modifier, juice beverage anti-mixing agent, meat product water retention, adhesive, dispersant, stabilizer, to prevent food discoloration and vitamin decomposition;
Sodium trimetaphosphate can be used for the preparation of Vc phosphate, which not only has the effect of vitamin C, but also overcomes the shortcomings of oxidation of vitamin C susceptible to light, heat and metal ions;
Strong complexing ability. It can form soluble complexes with calcium, magnesium, iron and other metal cations dissolved in water, remain inert, and make water soft, so it can be used as a water softener;
Sodium trimetaphosphate can be used as a buffer for hydrogen peroxide bleaching. If it is used as a detergent component, the pH of the detergent solution can be kept in the most suitable range, and if it is used as a light metal detergent, the harm of alkali can be prevented.
