Specification :

Sodium acid pyrophosphate, SAPP
Chemical formula: Na2H2P2O7
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 220centidegree, 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.
