Other names: SAPP
CAS number: 7758-16-9
Molecular formula: Na2H2P2O7
Molecular Weight: 221.95
Characteristics:
Sodium acid pyrophosphate is a white powder; Relative density 1.86; 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°C, it will be decomposed into sodium meta phosphate.

Use:
Sodium acid pyrophosphate 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.
MSDS: Available when required. |
