Character:It is colorless column crystal, odorless, slightly deliquescence. The relative density is 2.04 and melting point is 60 degree. It is easily soluble in water but insoluble in ethanol. If heated below 100 degree, it can dissolve in crystal water and convert to monohydrate salt. When heated to 100 degree, it will lose crystal water and change to anhydrous substances, which will become sodium metaphosphate if continue to be heated.
Uses: In food industry, it is used as buffering, character improving agent, emulsifier, nutrition supplement, antioxidant additive, brine penetrable agent, sugar clarifier, stabilizer, coagulant, fowl scalding agent.
Packing:It is packed with polyethylene bag as liner and a compound plastic woven bag as the outer layer. The net weight of each bag is 25kg.
