Abstract
The invention relates to a process for the production of xylose from a paper-grade hardwood pulp comprising the steps of extracting xylan contained in said pulp into a liquid phase, subjecting the xylan contained in the obtained liquid phase to conditions sufficient to hydrolyze xylan to xylose, and recovering the xylose, wherein the extracting step includes at least one treatment of an aqueous suspension of said pulp or an alkali-soluble material thereof with a xylanase enzyme.
