Abstract
Process for manufacturing xylitol and xylitol-rich products, characterized in that it consists of: PA1 enzymatically isomerizing at M.sub.1 D-xylulose syrup into syrup containing D-xylose and D-xylulose then, without extracting the xylose, PA1 catalytically hydrogenating this syrup at M.sub.2, resulting thus in a xylitol-rich syrup, said xylitol-rich syrup being either dehydrated, or subjected to chromatographic processing or to a treatment of extraction by crystallization at M.sub.3.
