実験手順

An isomaltose content syrup, obtained by the method in Example A-1, was hydrogenated in accordance with the method in Experiment 36, and the resulting mixture was in a usual manner decolored with an activated charcoal, desalted for purification with ion-exchange resins in H- and OH-forms, and concentrated to give a concentration of about 73%. The concentrate was spray dried in a usual manner to obtain a high isomaltitol content powder, containing 43.3% of isomaltitol, 37.8% of ring-opened tetrasaccharide, 13.8% of cyclotetrasaccharide, and 3.5% of other sugar alcohols, in a yield of about 80%.
