Sodium Acid Pyrophosphate （SAPP）

Chemical Name	Sodium Acid Pyrophosphate
Synonyms	Sodium acid pyrophosphate
Molecular formula	Na2H2P2O7
CAS NO.	7758-16-9
Standard Ｅxecuted	GB25567-2010

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 hygroscopic, 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 meta phosphate.

Application

As a leavening agent it is applied to roast foodstuffs to control the fermentation speed; When applied to instant noodles, it can shorten rehydration 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.

Packaging

Plastic knit bag or kraft bag, net weight 25kg. Besides, we can pack the goods according to the requirement of the client.
