Abstract:
The present invention is directed toward efficient, high-yield processes for making ascorbic acid, 2-keto-L-gulonic acid, and esters of 2-keto-L-gulonic acid. The processes comprise reacting the appropriate starting materials with a hydrolase enzyme catalyst such as a protease, an esterase, a lipase or an amidase.
