Superiority

1.character:

chemical formula : na2h2p2o7
molecular weight: 221.95

cas number: 7758-16-9

2.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°c, it will be decomposed into sodium meta phosphate.

3.uses:
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.
