Abstract
A method of recovering a sugar by separating a fermentation inhibitor and the sugar from a sugar solution containing the fermentation inhibitor, the method including: bringing the sugar solution containing the fermentation inhibitor into contact with a basic anion exchange resin filled into a column, followed by separation of the fermentation inhibitor and the sugar by a difference in retention time therebetween through use of water as an eluent, and separate recovery of a fraction containing the fermentation inhibitor and a fraction containing the sugar, wherein the basic anion exchange resin is previously treated with a solution containing the fermentation inhibitor.

A method of recovering a sugar by separating a fermentation inhibitor and the sugar from a sugar solution containing the fermentation inhibitor, the method comprising
- bringing the sugar solution containing the fermentation inhibitor into contact with an ion exchange resin filled into a column, followed by separation of the fermentation inhibitor and the sugar by a difference in retention time therebetween through use of water as an eluent, and separate recovery of a fraction containing the fermentation inhibitor and a fraction containing the sugar,
- wherein the ion exchange resin is previously treated with a solution containing the fermentation inhibitor such that the ion exchange resin is saturated with an arbitrary ion component in the sugar solution containing the fermentation inhibitor.
