Owing to the high impurity content of the XOS produced by directly enzymatic hy- Xylo-oligosaccharides (XOS) drolysis of xylan extracted from CS, subsequent reﬁning steps are essential. The present study was aimed to Ethanol gradient elution investigate desorption during ethanol elution to improve the quality and antioxidant activity of XOS from CS. Desorption The desorption was systematically investigated after optimizing the elution conditions. The results showed that Antioxidant activity it had an elution watershed when
