1、Chemical Name: SODIUM CITRATE
2、Molecular
Formula: Na3C6H5O7·2H2O
3、Molecular Weight:249.10
4、CAS: 68-04-2
5、Character: It is colourless or white
crystalline granule or crystalline powder, odorless, tastes salty and cool. It’s
soluble in water, difficulty in ethanol and slightly deliquescent in moist. PH
value is 7.6-8.6 in 5% aqueous solution. If heated to 150℃,it may lose crystal water.
6、Usage: In food processing industry, it is used as
buffer, chelating agent and nutrition supplement, emulsification, flavoring for
yoghurt. If in cool drink, it can abirritate the sourness of citrate acid,
prevent the acidification of dairy products. It is used as binder in cheese and
minced meat, gelatinize in jellies and syrup, emulsification and stabilizer in
cheese and ice cream.
7、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.
