White powder

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: Plastic knit bag or kraft bag, net weight 25kg or 50 kg.
Storage: Store at a cool, dry and well ventilated place. The package must be moistureproof and well sealed. Handle with care. During transportation, please avoid rains and strong sunshine. In case of fire, please use water、sandy soil or all kinds of fire extinguishers to quench it.
