摘要：
The invention relates to a method for the recovery of xylose from xylose-containing aqueous solutions that contain over 30 % by weight of xylose on dissolved dry solids. The solution is evaporated at low pressure to a solution supersaturated in respect of xylose, the solution is seeded, and the evaporation is continued at the boiling point of the solution until a crystal mass is obtained in which the xylose yield is 1 to 60 %, and the xylose crystals are recovered.
