XOS is a functional polysaccharide formed by connecting 2-7 xylose molecules with β-1, 4 glucosidic bond.
Molecular weight 132n+18 (n=2~7)
Molecular formula C5nH8n+2O4n+1
Range of MW 282~942

Xylo-oligosaccharide is a functional polysaccharide formed by connecting 2-7 xylose molecules with β-1, 4 glucosidic bond. It is a kind of high-efficient prebiotics.

Four key characters

  1. Proliferate bifidobacteria with high selectivity: the function is 10~20 times compared with other oligosaccharide, and it could be utilized by bifidobacteria prior, proliferate beneficial and inhibit breeding and reproduction of harmful bacteria.

  2. Hardly decomposed by human digestive enzyme : Digestive examination with spit, gastric juice, pancreatic juice and small intestine enzyme juice show that every kind of digestive juice can not decompose the XOS, the energy is almost 0. It is neither influencing blood sugar density nor increasing the insulin of the blood sugar and can not form fats deposit. especially fits those who have obesity, diabetes, high blood pressure and so on.

  3. High stability against acid and heat: XOS is stable at PH=2.5~ 8, 100 ℃,covering the processes for mostly food.

  4. Effective intake: lowest effective dosage:0.4g/d

Property analysis


Main function

  1. Regulate the intestinal flora, the effective dose of xylo-oligosaccharide is the lowest and t is only 0.7g, so it is called “super- bifidusfactors”.

  2. Improve constipation and diarrhea, “dual-direction regulation”

  3. Strengthen immunity and anti bowel cancer

  4. Decrease blood pressure, serum cholesterol and blood sugar.

  5. Prevent tooth decay

  6. “Beneficial calcium factor” Promote calcium absorption


  1. Medicine and health product: For people who have gastrointestinal dysfunction, diabetes,   obesity, arteriosclerosis, dental caries and so on.

  2. Food: table food, baked food, condiment, dessert, cake, can, candy and so on

  3. Dairy and beverage: Milk powder, liquid milk, yoghurt, lactobacillus beverage,

  4. carbonated beverage and so on

  5. Feed: Feed additive which substitute antibiotics

Product variety: XOS-95P, XOS-70P, XOS-35P, XOS-20P, XOS-70L.
