Xylo-oligosaccharides (XOS) are functional oligosaccharides consisting of D-xylose molecules linked primarily by β-(1→4)-glycosidic bonds, typically with a degree of polymerization (DP) ranging from 2 to 10. They are non-digestible food ingredients that preferentially stimulate the growth of beneficial gut bacteria,particularly Bifidobacterium and Lactobacillus specie
