Chemical Name: Sodium Acid Pyrophosphate;Disodium Dihydrogen Pyrophosphate
Molecular formula: Na2H2P2O7
CAS NO.: 7758-16-9
Ref. Standard: HG2928-1999
production capacity:3000 t/a
Properties: White powder or granular; Bulk 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 metaphosphate.

Application: 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.
