To produce a xylooligosaccharide using a xylanase, a xylanase having a low β-xylosidase activity should be used. Under these circumstances, the present invention has been completed on the basis of the finding that, in a process for producing a sugar solution and a xylooligosaccharide in parallel, a xylanase having a low β-xylosidase activity can be prepared at a low cost by recovering a cellulase having been used in a sugar solution production step and reusing the cellulase in a xylooligosaccharide process. |
