Erythorbic acid product description

It is a stereoisomer of vitamin C, so it is similar to vitamin C in chemical properties. The appearance is white to light yellow or crystal powder, odorless and sour, with a melting point of 166-172 ° C. it decomposes and gradually turns black when exposed to light. In dry state, it is quite stable in the air, but it deteriorates rapidly when exposed to the atmosphere in the solution. It has almost no physiological activity of ascorbic acid. Its antioxidant performance is better than ascorbic acid, but it has poor heat resistance and strong reducibility. Heavy metal ions can promote its decomposition. It is easily soluble in water, with a solubility of 40g / 100ml at normal temperature, soluble in ethanol, 5g / 100mL, insoluble in glycerol and insoluble in benzene. The pH value of 1% aqueous solution is 2.8.
