Product Description

Sodium Acid Pyrophosphate(SAPP)
E450(I)

Molecular formula: Na₂H₂P₂O₇
Molecular weight: 221.95
CAS Number: 7758-16-9
Other Name: Disodium Pyrophosphate; Disodium Dihydrogen Pyrophosphate;DisodiumDihydrogen Diphosphate
CNS.:15.008
                                                                               
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 220ºC, it will be decomposed into sodium meta phosphate.
Application: 
Buffer; emulsifier; leavening agent; sequestrant. 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.
