Procedimiento para la fabricación de una solución de azúcar

摘要

By filtering an aqueous sugar solution obtained by hydrolysis of a cellulose-containing biomass through an ultrafiltration membrane having a molecular weight cutoff of 600 to 2,000 to remove fermentation inhibitors into the permeate side and collect a sugar liquid from the feed side, a sugar liquid containing only a very small amount of fermentation inhibitors can be produced.
