Abstract: A method for saccharifying cellulose includes introducing a cellulose-containing raw material and a reaction solution into a saccharification tank, introducing an enzyme into the reaction solution in the saccharification tank, disposing an adsorption sheet on the liquid surface of the reaction solution, and decomposing the cellulose with the enzyme by stirring the reaction solution to produce a saccharide. The adsorption sheet adsorbs an oil component released from the raw material to the liquid surface of the reaction solution during the production of the saccharide.
