Abstract
The invention relates to a method of producing xylitol and erythritol from arabinoxylan-containing material. According to the invention, the arabinoxylan-containing material is hydrolyzed and xylose and arabinose are separated from the obtained hydrolysate, whereafter the xylose is reduced to xylitol, and the xylitol is recovered, and the arabinose is subjected to alkaline oxidation to obtain erythronic acid which is reduced to erythritol, and the erythritol is recovered.
