Abstract
The present invention provides a method for purifying cellobiose which comprises the steps of (A) preparing a cellobiose-containing sugar solution; (B) increasing the rate of cellobiose present in the sugar solution relative to the total saccharides present therein up to at least 50% by mass; and (C) crystallizing cellobiose; and a method for preparing cellobiose having a high content of the α-anomer thereof which comprises the step of drying a cellobiose-containing sugar solution having a rate of cellobiose of at least 90% by mass relative to the total saccharides present therein while maintaining the sugar solution at a temperature ranging from 80 to 95° C. These methods of the present invention permit the economical preparation of cellobiose having considerably improved purity and recovery rate, without using any complicated process. Moreover, the present invention also permits the preparation of cellobiose highly soluble in water.
