Sell Sodium acid pyrophosphate(SAPP)

Description

Chemical formula: Na2H2P2O7
Molecular weight: **1.*5
Standard executed: Standard executed: Tech grade (national standard)  Food grade (HG ********9)
CAS Number: ********9
Properties:
White powder or granular; Relative density 1.*6g/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 **0℃, 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 *5kg, *0kg, ***0kg net bags, store at a cool, dry and well ventilated place.
