Process in Isolation and Purification of Xylooligosaccharides

Isolation and Purification techniques of xylooligosaccharides are reviewed.Xylooligosaccharides considered as non digestible oligosaccharides(NDO) can specifically promote the growth of bifidobacteria within the intestinal tract and can be extensively used in food industry and feed industry.The methods of isolation and purification xylooligosaccharides include chromatography (e.g.gel filtration chromatography,ion exchange chromatography and adsorption chromatography),membrane separation (e.g.ultrafiltration,nanofiltration and reverse osmosis) and biological method.Xylooligosaccharides are purified mainly by membrane and chromatography techniques.The main methods of isolation xylooligosaccharides are gel filtration chromatography and adsorption chromatography.;
