PROBLEM TO BE SOLVED: To provide a method for obtaining a lignin composition, in a step containing a saccharification step of a lignocellulosic biomass material.SOLUTION: A processed object which is subjected to a saccharification processing step, from a lignocellulosic material, is subjected to solid liquid separation, then the obtained solid content is subjected to acid processing, for separating a lignin composition. The solid content or lignin composition may be subjected to derivation processing.SELECTED DRAWING: Figure 1 |
