Abstract: The present disclosure relates to a method for separating sugars and acids with reduced energy consumption, including a step of diffusively dialyzing a first acid hydrolysate obtained by saccharifying biomass with an acid solution, thereby preparing a second acid hydrolysate wherein the concentration of the acid solution contained in the acid hydrolysate is decreased; and a step of electrolyzing the second acid hydrolysate, thereby separating sugars from the acid solution, which is advantageous in that less energy is consumed, the separated acid solution can be recycled directly without further treatment due to high concentration and loss of sugars can be minimized.
