Publikováno v: Food and Bioproducts Processing. 87:197-207
A primary hydrolysis treatment (auto or acid-catalysed) of Eucalyptus globulus wood was performed before the cooking stage to extract part of the hemicelluloses that otherwise would be dissolved in the kraft liquor and burned. As xylose was the main
