Abstract
A pretreatment method for saccharification of plant fiber materials includes: immersing the plant fiber material in a solution that contains an organic solvent, in which a cluster acid is dissolved, prior to saccharifying cellulose contained in the plant fiber material; and distilling off the organic solvent from the immersed plant fiber material to obtain a pretreated mixture that contains the cluster acid and the pretreated plant fiber material.
