When oligosaccharides such as maltopentaose are separated by liquid chromatography, a large amount of an aqueous solution of an organic solvent such as ethanol or isopropyl alcohol is used as an eluent. In this preparative separation operation, the eluate other than the recovered fraction of the target component is discarded, resulting in waste liquid. This waste liquid is a mixed liquid containing a solvent such as ethanol and oligosaccharide or, depending on the composition of the stock solution, a higher molecular weight dextrin or the like in addition to the oligosaccharide.
