Abstract

See full text

The object of the present invention is to provide a method and a process for producing 2-O-α-glucopyranosyl-L-ascorbic acid where 5-O-α-glucopyranosyl-L-ascorbic acid and 6-O-α-glucopyranosyl-L-ascorbic acid are not formed or formed in such a small amount that the formation of these can nor be detected. The present invention solves the above object by providing a process for producing 2-O-α-glucopyranosyl-L-ascorbic acid comprising the steps of allowing α-isomaltosyl glucosaccharide-forming enzyme together with or without cyclomaltodextrin glucanotransferase (EC 2.4.1.19) to act on a solution comprising L-ascorbic acid and, an α-glucosyl saccharide to form 2-O-α-glucopyranosyl-L-ascorbic acid and collecting the formed 2-O-α-glucopyranosyl-L-ascorbic acid.
