    • 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。

    • An object of the present invention is to provide a lactosucrose high content saccharide which comprises 70% or more of lactosucrose, on a saccharide composition basis, with a lower content of 1-kestose and fructosyl lactosucrose as by-products. Another object of the present invention is to provide processes for producing a lactosucrose high content saccharide and high purity lactosucrose containing 90% or more of lactosucrose, on a saccharide composition basis, which are feasible for industrial production. Further object of the present invention is to provide a solid lactosucrose with low hygroscopicity and a solid composition comprising the same. The present invention solves above objects by providing a lactosucrose high content saccharide comprising 70% or more of lactosucrose and less than 3% of the total amount of 1-kestose and fructosyl lactosucrose, on a saccharide composition basis; a process for producing the lactosucrose high content saccharide, comprising the steps of allowing β-fructofuranosidase, derived from a microorganism belonging to the genus Bacillus, and sucrose-unassimilable yeast to contact with an aqueous solution containing sucrose and lactose to obtain a reaction mixture comprising 70% or more of lactosucrose and less than 3% of the total amount of 1-kestose and fructosyl lactosucrose and collecting the resulting lactosucrose high content saccharide; a process for producing a high purity lactosucrose, comprising the steps of subjecting the lactosucrose high content saccharide to a chromatography using a resin and collecting fractions containing 90% or more of lactosucrose, on a saccharide composition basis; a process for producing crystalline lactosucrose; and various solid compositions prepared by incorporating the crystalline lactosucrose.
