Abstract
The present invention relates to a method of producing xylose by chromatographic separation of the xylose from a sulphite cooking liquor containing for example xylose and xylonic acid. The xylose yield of the separation is affected by the xylonic acid and xylose content in the cooking liquor used in the separation and the amount of base cation used in the sulphite cooking.
