US Patent 8927038 (Arabino)xylan oligosaccharide preparation

The present invention relates to preparations comprising (arabino)xylan oligosaccharides with average degree of polymerisation between 4 and 10 and average degree of arabinose substitution between 0.15 and 0.35, which beneficially modulate the intestinal flora, such preparation comprising both xylo- and arabinoxylo-oligosaccharides. Preferably, the arabinoxylooligosaccharides are substituted in part by hydroxycinnamic acids and exert antioxidant effects. Furthermore, it is preferred that the preparations according to the present invention have a nitrogen content below 0.16% (w/w) in order to ensure good organoleptic and color properties, particularly upon heating said preparations.
