Chemical formula : Na2H2P2O7
Molecular Weight : 221.95
Standard executed : GB25567-2010 (FOOD GARDE)
【Properties 】
White 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, 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 net WPP/PE bags, stored at a cool dry and well ventilated place.
