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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
