制备2-O-α-D-吡喃葡萄糖基-L-抗坏血酸的方法

Process for producing 2-O-alpha-D-glucopyranosyl-L-ascorbic acid
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（中）：

本发明的目的是提供一种生产2-O-α-吡喃葡萄糖基-L-抗坏血酸的方法和方法，其中5-O-α-吡喃葡萄糖基-L-抗坏血酸和6-O-α-吡喃葡萄糖基 - L-抗坏血酸不是以这样的少量形成或形成，也可以不形成。 本发明通过提供一种生产2-O-α-吡喃葡萄糖基-L-抗坏血酸的方法来解决上述目的，其包括以下步骤：将α-异麦芽糖基葡萄糖形成酶与或不与环糊精葡聚糖转移酶（EC 2.4.1.19）一起 作用于包含L-抗坏血酸和α-葡萄糖基糖的溶液中以形成2-O-α-吡喃葡萄糖基-L-抗坏血酸并收集形成的2-O-α-吡喃葡萄糖基-L-抗坏血酸。
