Vorschrift

A commercially available aqueous solution of high purity maltose having the same sugar composition used in the first step of Example 2 was adjusted to have a concentration of 50%, and then reduced under the existence of Raney nickel catalyst at a hydrogen pressure of 100 kg/cm2 and 130° C. for 1.0 hour, to obtain aqueous solution of maltitol. The sugar composition in the solid component of the resulting aqueous solution of maltitol was that maltitol was 81.0%, sorbitol was 0.5%, oligosaccharide alcohol which was equal or more than DP3 was 18.5%.
