Sodium pyrophosphate is a white powder that is soluble in water but insoluble in alcohol. It has a relative density of 2.45 and a melting point of 890 ℃. The aqueous solution is weakly alkaline and easily deliquests in air. The aqueous solution is relatively stable at 70 ℃, and when boiled, it hydrolyzes into disodium hydrogen phosphate.
Application:
Sodium pyrophosphate is used in the food industry as a water retention agent, quality improver, leavening agent, acidity regulator, emulsifier, buffering agent, chelating agent, etc. Used as a product quality improver for canned goods, fruit juice beverages, dairy products, soy products, soy milk, etc
