Abstract
A sugar liquid containing only very small amounts of fermentation-inhibiting substances is produced by a method for producing a sugar liquid using a cellulose-containing biomass as a raw material, the method including: (1) a step of hydrolyzing a cellulose-containing biomass to produce an aqueous sugar solution; and (2) a step of filtering the obtained aqueous sugar solution through a nanofiltration membrane and/or reverse osmosis membrane to collect a purified sugar liquid from the feed side, while removing fermentation-inhibiting substances from the permeate side.
