A method is disclosed for the production of xylitol from a xylose and/or xylan containing material. A solution containing xylitol and other hexoses is fermented with a yeast strain capable of converting free xylose to xylitol and other free hexoses present to ethanol, with the xylitol subsequently separated by chromatographic separation means.
