Product overview

Properties White crystalline powder.

Melting point 880℃ Relative density 2.534 Solubility easily soluble in water, solubility in 100g water at 20℃ is 6.23g, its aqueous solution is alkaline; insoluble in alcohol.

Applications

In terms of food, it is used as a quality improver for cans, fruit juice drinks, dairy products, etc. It has the properties of polymerized pyrophosphate, emulsifying, dispersing, preventing fat oxidation, improving the viscosity of casein, and inhibiting the food easy to be oxidized and fermented. Crystalline and anhydrous sodium pyrophosphate are rarely used alone, and are generally used together with other condensed phosphates after preparation.

In industry, the mixed preparation of sodium pyrophosphate and sodium polyphosphate can be used as elastic reinforcement.

Packaging
