Difference between xylo oligosaccharides and Fructooligosaccharide


Xylo-oligosaccharides is a type of functional polymer sugar composed of 2-7 xylose molecules bonded with β (1-4) glycosidic bonds.Compared with the commonly used soy oligosaccharides, Fructooligosaccharide and oligo maltose, it has unique advantages, and it can selectively promote the proliferation of intestinal bifidobacteria. The bifidus factor is 10-20 times as much as other polymeric sugars.

Fructooligosaccharide,also named FOS, is a carbohydrate formed by the linkage between 2~5 fructose groups and a terminal group with a glucose group as the backbone. That is, the 1~4 fructose based on the beta -2, 1 keys connected to the D- fructose base on sucrose, the formation of sugarcane fruit three sugar (GF2), sugarcane fruit four sugar (GF3), sugarcane fruit five sugar (GF4) and sugarcane fruit six sugar (GF5) mixture. Fructooligosaccharide products generally contain a small amount of sucrose, fructose,and glucose.


Difference between xylo oligosaccharides and Fructooligosaccharide

1. For Xylo-oligosaccharides,Daily effective intake is 0.7-1.4g.

  For Fructooligosaccharide,Daily effective intake is 5.0-20.0g.

2.Xylo oligosaccharides do not contain sucrose and fructose. Diabetics can be assured to use it. In addition, Fructooligosaccharide products usually contain small amounts of sucrose, fructose and glucose. Diabetics should be used with caution.

3.Xylo oligosaccharides can not absorbed by the body, and all are selected by bifidobacteria, but Fructooligosaccharide are absorbed by the body, so they are not all used to produce bifidobacteria.
