Vitamin C (Ascorbic Acid) is an essential nutrient for humans and certain other animal species. It is extensively used in nutritional products and health care and dietary supplements. Vitamin  (ascorbic acid) is also widely used as a food additive. Vitamin has been produced commercially by extraction from plants, by chemical synthesis, by fermentation and by mixed fermentation/chemical synthesis methods. Traditionally the production of ascorbic acid was carried out by Reichstein process developed in 1933, which is a mixed fermentation/chemical synthesis method.

In China, all Chinese producers use the two-stage fermentation process developed indigenously by Chinese researchers.
