SODIUM ACID PYROPHOSPHATE

Chemical formula : Na2H2P2O7 Molecular weight: 221.95 Properties: White crystal powder;Relative density 1.86;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. 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. Packing and storage: Packed in 25 kg net WPP/PE bags. It must be stored in places well ventilated and dry.
