发明名称 PROCESS FOR PRODUCING 2-O-alpha-D-GLUCOPYRANOSYL-L-ASCORBIC ACID
摘要 A method of reaction for yielding 2-O-alpha-D-glucopyranosyl-L- ascorbic acid. In this method, 5-O-alpha-D-glucopyranosyl-L-ascorbic acid and 6-O-alpha-D-glucopyranosyl-L-ascorbic acid are not generated or are generated in such a small amount that the generation of these cannot be detected. Also provided is a process for producing 2-O-alpha- D-glucopyranosyl-L-ascorbic acid which employs the reaction method. The process for producing 2-O-alpha-D-glucopyranosyl-L-ascorbic acid is characterized by causing an alpha-isomaltosyl glucoglucide-producing enzyme or a combination of an alpha-isomaltosyl glucoglucide-producing enzyme and cyclomaltodextrin glucanotransferase (EC 2.4.1.19) to act on a solution containing L-ascorbic acid and alpha-glucosyl saccharide compound to yield 2-O-alpha-D-glucopyranosyl-L-ascorbic acid and collecting it.
