摘要: In the present invention, a sugar alcohol can be efficiently produced from a cellulose-containing biomass by carrying out a step (1) of filtering an aqueous sugar solution, which is obtained by hydrolysis of a cellulose-containing biomass, by passing the solution through a separation membrane having a molecular cut-off of 300-800 so as to remove catalyst poisons to the non-permeate side and collecting a sugar solution from the permeate side, and a step (2) of subjecting the sugar solution obtained in step (1) to a hydrogenation reaction in the presence of a metal catalyst.
