Sodium Acid Pyrophosphate(SAPP)

Sodium Acid Pyrophosphate(SAPP)
Product Detailed
As a leavening agent it is applied to roast foodstuffs to control the fermentation speed

Sodium Acid Pyrophosphate(SAPP)

 

Chemical formula:Na2H2P2O7

Molecular weight:221.95

Standard executed:HG2928-1999

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°C, it will be decomposed into sodium meta phosphate.

Uses: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:Packed in 25kg,50kg,1000kgnet bage,store at a cool, dry and well ventilated place.
