Title:
METHOD FOR PRODUCING SUGAR LIQUID
Document Type and Number:
WIPO Patent Application WO/2010/067785
Kind Code:
A1
Abstract:
Provided is a method for producing a sugar liquid using a cellulose-containing biomass as the starting material. Sugar liquid having a very low fermentation-inhibiting substance content is produced by a method comprising (1) a step in which a cellulose-containing biomass is hydrolyzed to produce an aqueous sugar solution and (2) a step in which the resulting aqueous sugar solution is filtered through a nanofiltration membrane and/or reverse osmosis membrane, the pure sugar liquid is recovered from the unpermeated side, and the fermentation-inhibiting matter is removed from the permeated side.
