Chemical Formula: Na2H2P2O7
Molecular Weight: 221.95
CAS Number:7758-16-9
Disodium Pyrophosphate 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, disodium pyrophosphate will be hydrolyzed into phosphoric acid; SAPP disodium pyrophosphate is hydroscopic, and when absorbing humidity it will become into a product with hexa-hydrates; If sodium acid pyrophosphate is heated at a temperature above 220℃, sodium acid pyrophosphate will be decomposed into sodium meta phosphate.

Disodium Pyrophosphate Uses:
As a leavening agent disodium dihydrogen pyrophosphate 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, SAPP may shorten fermentation time, lower the breakage, make the porous space in good order and therefore lengthen the shelf life.
Packing and Storage:
Packed in 25kg,50kg,1000kgnet bage,store at a cool, dry and well ventilated place. |
