摘要： Provided is a method for manufacturing crystalline isomaltulose from sucrose, comprising the steps of: 1) contacting an α-glucosyltransferase enzyme to aqueous sucrose solution or slurry under the condition wherein the α-glucosyltransferase enzyme is active; in which said condition is maintained after the concentration of isomaltulose in the reaction mixture reaches the point at which crystals are formed, and 2) separating the reaction mixture into crystalline isomaltulose and remaining syrup. According to the present invention, enzymatic conversion of sucrose and crystallization of isomaltulose are carried out simultaneously in a same reaction vessel. In addition, the enzyme can be used repeatedly.

摘要： Maltitol crystals containing sugar crystals other than maltitol which have excellent solubility, almost no hygroscopicity, do not become bulky when they are stored or transported because they have a large bulk density, a small difference between packed bulk density and loose bulk density thereof and excellent flowability. The maltitol crystals containing sugar crystals other than maltitol have a loose bulk density of particles having a particle size of 20 to 50 mesh after grinding and classification of more than 0.750 g/cd and 0.850 g/cc or less.
