Erythorbic acid or erythorbate, formerly known as isoascorbic acid and D-araboascorbic acid, is a stereoisomer of ascorbic acid.

       And its chemical properties have many similarities with Vc, but as an antioxidant, it has the inimitable advantage that Vc do not have: First, it is superior to the anti-oxidation than Vc, therefore, mixed the Vc, it can effectively protect the properties Vc component in improving the properties have very good results, while protecting the Vc color. Second, higher security, no residue in the human body, participating in metabolism after absorb by human body, which can be transformed into Vc partially. In recent years, Chinese medicine take it as complementary information be used in Vc film, Vc Yinqiao-Vc and health care products, and obtain good effect.

      Non toxic、non-pollution, prevention of cancer and no residue, it is a perfect natural green food additive.
