Product Description

Introduction
D-isoascorbic acid is a natural, green and highly effective food antioxidant, which plays a considerable role in improving the stability of food and extending the storage period. As an isomer of Vc, D-isoascorbic acid has many similarities in chemical properties with Vc, but as an antioxidant, it has advantages that Vc does not possess. First of all, its oxidation resistance is better than that of Vc. Therefore, when used with VcChemicalbook, it can effectively protect the medicinal components of Vc, and has a good effect in improving the medicinal properties, while protecting the color of Vc. Second, the safety is high, there is no residue in the human body, and the body participates in metabolism after ingestion, which can be partially converted into Vc. In recent years, it has been applied to Vc tablets, Vc Yinqiao tablets and Vc health products as a kind of auxiliary materials for medicine, and has achieved good results.APPLICATION&FUNCTION
Erythorbic acid can be used as food anti-oxidant; as auxiliary material of drug or health supplies; as stabilizer of chemical raw materials; as except oxygen, and anti-corrosion, and except scale solvent of important component; as electrolytes of electrolytic and plating; as metal micro-powder of production and heavy metal of recycling. In addition, erythorbic acid is also applied to textile chemicals manufacturing, building materials and daily-use chemical industry.
