Sodium pyrophosphate CAS 7758-16-9
Disodium dihydrogen pyrophosphate is flammable in the presence of H pore agent, and will emit toxic phosphorus oxide fumes when heated. Disodium dihydrogen pyrophosphate appears as a white monoclinic crystalline powder or a molten solid. The relative density is 1.86. Soluble in water, insoluble in ethanol. The aqueous solution is hydrolyzed to phosphoric acid by heating with dilute inorganic acid.

Disodium dihydrogen pyrophosphate can be used as a quality modifier, which can improve the complex metal ions, pH value and ionic strength of food, thereby improving the binding strength and water retention of food. Disodium dihydrogen pyrophosphate can be used as baking powder to control the fermentation speed and improve the production intensity. Used for instant noodles, reduce the rehydration time of the finished product, do not stick to rot. Used for biscuits and pastries, shorten the fermentation time, reduce the breakage rate of products, loose gaps neatly, can extend the storage period.
