Abstract: Provided is a method for producing a saccharified solution of wood-based biomass having toxicity reduced or removed, comprising the steps of: preparing a saccharified solution in which wood-based biomass has been pretreated by hydrolysis; and reducing toxicity in the saccharified solution using an electrochemical detoxification method. The method is capable of efficiently removing the toxicity of compounds which are produced during the pretreatment process and inhibit growth of microorganisms and fermentation. In addition, the method is capable of increasing the efficiency of production by minimizing sugar loss and additional costs during the toxicity removal process.
