Sodium Acid Pyrophosphate (SAPP)
Chemical NameSodium Acid Pyrophosphate
SynonymsSodium acid pyrophosphate
Molecular formulaNa2H2P2O7
CAS NO.7758-16-9
Standard ExecutedGB25567-2010
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 hygroscopic, 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.
As a leavening agent it is applied to roast foodstuffs to control the fermentation speed; When applied to instant noodles, it can shorten rehydration time and avoid stickiness and mushiness of the noodles; When applied to crackers or cakes, it may shorten fermentation time, lower the breakage, make the porous space in good order and therefore lengthen the shelf life.
