3\u3001Molecular Weight: <\/b><\/strong>Anhydrous: 141.96; Dihydrate: 177.99; Dodecahydrate: 358.14<\/p>\n

4\u3001CAS: <\/b><\/strong>Anhydrous: 7558-79-4; Dihydrate: 10028-24-7; Dodecahydrate: 10039-32-4<\/p>\n

5\u3001Character:<\/b><\/strong>\u00a0It is white or colorless rhombic crystalline or prismatic crystal. It\u2019s easily soluble in water, but insoluble in ethanol. The relative density is 1.52\u00a0and melting point is 34.6\u2103. If heated to 180\u2103, it will lose crystal water and convert to anhydrous.<\/p>\n

6\u3001Usage: <\/b><\/strong>In food industry, it is used as agent for baking to avoid oxidation stain and as emulsifier in dairy product to prevent egg white from solidification. It is also used as emulsifier and chelating agent for solid drinks.<\/p>\n

7\u3001Packing:<\/b><\/strong>\u00a0It is packed with polyethylene bag as inner layer and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.<\/p>\n

8\u3001Storage and Transport:<\/b><\/strong>\u00a0It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.<\/p>\n
