1.Chemical Name: magnesium sulfate
2.Molecular Formula: MgSO4·7H2O, dry，MgSO4·nH2O
3.Molecular Weight: 246.47(Heptahydrate)
4.CAS: 10034-99-8(Heptahydrate)，7487-88-9(Anhydrous)
5.Character: It’s colorless prismatic or needle-shaped crystal. It’s
odorless. It tastes cool, salty and bitter. Relative density is 2.65. It’s
steady in damp air under 48℃. When it is in warm and hot air, it is easily
effloresce. It is easily soluble in water (119.8%, 20℃) and glycerine，slightly
soluble in ethanol. The aqueous solution is neutral.
6.Usage: In food industry, it is used as nutritional supplement,
solidification, the flavor increase，process helper，brew additive. It is used as
nutritional supplement to improve ferment in brew and the improvement of the
synthesizes drink taste(0.002%). It also can adjust the aqueous degree of
hardness.
7.Packing: It is packed with polyethylene bag as inner, and a composite
paper bag as the outer layer. The net weight of each bag is 25kg.
