Abstract
The present invention relates to an environmentally friendly, simple and economic process for producing xylose. The process comprises the steps of: a) countercurrently extracting tropical fruit biomass by hydrolysis with sulfuric acid to obtain a high-concentration xylose extract; b) adjusting the extract to a pH of 1.5-2.5 and decolorizing and filtering the pH-adjusted extract; c) desalting the filtrate in an electrodialysis device; and d) recycling a waste sulfuric acid solution recovered from step c), to step a), and concentrating and directly recovering the desalted filtrate to obtain xylose crystals.
