Manufacturing Process
Vitamin C has been produced economically by evocation from plants, by chemical unification, by fermentation and by mixed fermentation/chemical unification methods. The manufacture of vitamin C can be carried out in two ways. Figure 1 shows the main steps in the two processes. Vitamin C cannot be produced by humans but is available in many other types of food. Citrus fruits are the best known sources of vitamin C, but red and green peppers, tomatoes, potatoes, and other vegetables are also excellent sources.
Most organisms are able to produce their own vitamin c internally with the exception of rats and guinea pigs. (web.archive.org)
The two step fermentation process was developed in China and is used by all chinese producers. In this process, a second fermentation replaces the chemical reactions used to produce DAKS in the Reichstein method. This fermentation results in a different product, KGA. The last 2 chemical steps are the same for both processes. The two step fermentation process has less use of toxic solvents. (web.archive.org)

Fermentation: a chemical reaction in which a micro-organism or enzyme causes an organic compound to split into simpler substances.
