Acid Sodium Pyrophosphate

Sodium acid pyrophosphate ◆Na2H2P2O7 ◆Technical / Food grade ◆Powder ◆CAS Number 7758-16-9 Used as acidity- adjuser ,emulsifier ,complexing,expanding agent in food industry. Used as a leavening agent, used for baking food, to control the fermentation speed; For noodles, it can shorten the rehydration time of the finished product, and make the noodles not sticky or rotten; Used in biscuits and cakes, it can shorten the fermentation time, reduce the product breakage rate, loosen the gaps neatly, and prolong the storage period.SAPP Sodium Acid Pyrophosphate :White powder or granular;Relative density 1.86g/cm3;Soluble in water and insoluble in ethanol; If its aqueous solution is heated together with diluted inorganic acid, it will be hydrolyzed into Phosphoric Acid; It is hydroscopic, and when absorbing humidity it will become into a product with hexa-hydrates; If it is heated at a temperature above 220℃, it will be decomposed into sodium meta phosphate.
