Molecular formula: Na2H2P2O7

Molecular weight: 221.95

National Standard: GB 25567-2010

CAS Number: 7758-16-9

Other Name: Disodium Pyrophosphate; Disodium Dihydrogen Pyrophosphate;DisodiumDihydrogen Diphosphate

INS: E450I

CNS.:15.008

ROR:15-22-28-40


Properties

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.


Application

Buffer; emulsifier; leavening agent; sequestrant. As a leavening agent it is applied to roast foodstuffs to control the fermentation speed; When applied to instant noodles, it can shorten water resetting 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.
