    摘要： 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.

    摘要： An object of the present invention is to provide novel methods for forming glucosyl-transferred polyalcohols, glucosyl-transferred glucuronic acid, and glucosyl-transferred derivatives of glucose whose C-6 hydroxyl group bound to a saccharide by using an enzymatic reaction. The present invention solves the above object by providing a method for transferring a glucosyl residue to polyalcohols, glucuronic acid and/or derivatives of glucose whose C-6 hydroxyl group bound to a saccharide, comprising a step of: allowing a trehalose phosphorylase to act on a saccharide containing glucose as a component sugar and one or more polyalcohols selected from the group consisting of inositol, ribitol, erythritol, and glycerol; glucuronic acid and/or a salt thereof; and/or one or more derivatives of glucose whose C-6 hydroxyl group bound to a saccharide selected from the group consisting of isomaltose, gentiobiose, melibiose, isomaltotriose, and isopanose.
