Abstract

A process for extracting xylitol from the end syrups of the xylitol crystallization by subjecting the end syrup to chromatographic separation, whereby it will be decomposed into two or more fractions, the first fraction containing mainly the polysaccharides and polysaccharide alcohols and the subsequent fractions containing essentially the pentitols and hexitols.
