■ Specifications
Product Name :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℃, 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 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.
