Vorschrift

A commercially available aqueous solution of high purity maltose (mfd. by NIHON SHOKUHIN KAKO K.K., concentration: 60%, sugar composition in the solid component: maltose: 81.6%, glucose: 1.5%, sugar of equal or more than DP3: 16.9%) was reduced under the existence of Raney nickel catalyst at a hydrogen pressure of 100 kg/cm2 and 130° C. for 120 minutes, to obtain aqueous solution of maltitol.
