Sodium acid pyrophosphate (SAPP)

Chemical formula: Na2H2P2O7

Molecular weight: 221.95

CAS Number: 7758-16-9

 

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 centigrade, it will be decomposed into sodium meta phosphate.

 

Application:

Used 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.

 

Packing and storage:

In 25kg, 50kg, 1000kg net bags, store at a cool, dry and well ventilated place.
