In the production of ethanol from woody materials through enzymatic saccharification, the prerequisite is the removal of lignin for converting cellulose into monosaccharide. Producing fine-crushed material by a fine-crusher, quantitatively evaluating its shape or surface texture by an image analysis, and subjecting it to subcritical water treatment constitute a new preprocessing technology for the removal of lignin. The image analysis revealed that fine-crushing for exposing the wood fibre results in a high removal of lignin. The exposure of wood fibre increased with increasing moisture content of material. The most favourable fine-crushed material for subcritical water treatment was produced by the use of a small pore size of punching sieve and a high moisture content of material.
