2.Character:

 a.The Erythorbic Acid is the stereo isomer of Vitamin C, so its chemical character is same to the Vitamin C.

The Erythorbic Acid is white to light yellow white crystal or crystal powder, odorless, has sourness, the melting point is 166~172<C

b. In dry state, it is rather stable in the air, but in the solution, when exposed to the air, it will quickly metamorphose, hardly have the physiology activity actions of the ascorbic acid.

c.The Erythorbic Acid is easily dissolved in water, the dissolution value being 40g/100ml at normal temperature, hardly dissolved in glycerin, not dissolved in ethanol and benzene, its 1% water solution PH value is 2.8.

 

d.Antioxidation property: the antioxidation property of the Erythorbic Acid is great larger than the Vitamin C, has no effects to identify Vitamin C, but it will not inhibit the body to absorb and use the Erythorbic Acid. The body culls the Erythorbic Acid and changes it into Vitamin C inside the body.

      

 

3.Packing and cheking
