    • The invention provides a process for enabling the production of a particulate composition containing anhydrous crystalline ascorbic acid 2-glucoside that does not significantly cake even when the production yield of ascorbic acid 2-glucoside does not reach 35% by weight. The process for producing a particulate composition containing anhydrous crystalline ascorbic acid 2-glucoside, which comprises allowing a CGTase to act on a solution containing either liquefied starch or dextrin and L-ascorbic acid and then allowing a glucoamylase to act on the resulting solution to obtain a solution with an ascorbic acid 2-glucoside production yield of at least 27%, purifying the obtained solution to increase the ascorbic acid 2-glucoside content to a level of over 86% by weight, precipitating anhydrous crystalline ascorbic acid 2-glucoside by a controlled cooling method or pseudo-controlled cooling method, collecting the precipitated anhydrous crystalline ascorbic acid 2-glucoside, and ageing and drying the collected anhydrous crystalline ascorbic acid 2-glucoside.
    • 本发明提供了一种能够生产含有抗坏血酸2-葡萄糖苷的无水结晶抗坏血酸2-葡萄糖苷的颗粒组合物的方法,即使当抗坏血酸2-葡萄糖苷的产率不达到35重量%时也不显着。 制备含有无水结晶抗坏血酸2-葡萄糖苷的颗粒组合物的方法,其包括使CGT酶作用于含有液化淀粉或糊精和L-抗坏血酸的溶液,然后使葡糖淀粉酶作用于所得溶液以获得 将抗坏血酸2-葡萄糖苷产率至少为27%的溶液,纯化得到的溶液,将抗坏血酸2-葡萄糖苷含量提高至86重量%以上,将无水结晶性抗坏血酸2-葡萄糖苷通过 控制冷却方式或假控制冷却方法,收集沉淀的无水结晶抗坏血酸2-葡萄糖苷,并对收集的无水结晶抗坏血酸2-葡萄糖苷进行老化和干燥。

    • 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.
    • 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。
