Chemical Formula:Na4P2O7 Molecular Weight:265.9 Voluntary Standard:HG/T2968-1999(Industrial Grade) GB8848-88(Food Industry)

Properties: White powder; Soluble in water but insoluble in ethanol and ammonia; specific gravity is 2.534 and melting point is 880; Its aqueous solution, which is of alkalinity, when boiled, will be hydrolyzed to Na4P2O7. Usage:Used as water softening agent, synthetic detergent, metal ion sequestrant, dispersant, boiler water treatment, vegetable fiber bleaching agent, buffer of electrolysis and electroplate. In food industry it is used as buffering agent, emulsifier, nutrition ingredients and quality improver. It can enhance PH of the meat and strengthen water holding capacity (WHC) of the meat, it can heighten processing performance of cooked wheaten food and improve the quality of cooked wheaten food; it can avoid changing the color of processed fruit in making tinned fruit.Package: In double layer bags of 25Kg net. It must be stored in places well ventilated and dry. Specifications:
