What is Xylooligosaccharides (XOS)? Compared with the commonly used soybean oligosaccharides, fructooligosaccharides, isomalto-oligosaccharides, etc., it has unique advantages. Xylooligosaccharides, also known as xylo-oligosaccharides, are functional polymeric sugars composed of 2-7 xylose molecules combined with β-1,4 glycosidic bonds. Xylooligosaccharides is one of the most powerful varieties of polysaccharides for proliferating bifidobacteria. There is no enzyme in the human gastrointestinal tract to hydrolyze xylo-oligosaccharides, so its It can directly enter the large intestine and is preferentially used by bifidobacteria to promote the proliferation of bifidobacteria while producing a variety of organic acids. Lower the intestinal PH value, inhibit the growth of harmfu…
