Product Description


Food grade--M.W:2000Da

medicine grade--M.W:<1500Da

Agriculture grade--M.W:2000-3000Da


English name: Chitosan Oligosaccharide

Chitosan Oligosaccharides, whose degree of polymerization is lower than 20, were obtained through the enzymatic degradation of chitosan, a natural polysaccharides which are combined with β-1, 4 of Glucosamine.


Chitosan Oligosaccharidesare yellow brown powder, and water-soluble with good stability,natural, pure green, non-toxic, harmless features.

Biological functions

- Immune-regulation activity

- Control of hypertension and Cholesterol regulation
- Function for discharge of radioactive material
- Function for intestinal disorders, digestion promotion and intestinal microflora     regulation
- Antibacterial function
Promotion of calcium absorption
- Moisture retention
- Antitumor effect

Application fields

1. Medical industry

Chitosan Oligosaccharides has a variety of biological function. According to its medical function, there will be more drugs derived from alginate oligosaccharide.

·Antibacterial diminish inflammation drugs

·Accelerate wound healing drugs

·Sustained-release drugs

2. Food industry

Because of its high solubility and bioactivity, Chitosan Oligosaccharides can be used as food materials or food additives.

Chitosan Oligosaccharides have the function of intestinal immune regulation, detoxification, lowering blood lipids and glucose , anticoagulation, anti-inflammation and Immune system regulation, and can be used as food of patients with obesity, diabetes, colorectal cancer, and habitual constipation. Chitosan Oligosaccharides can also be added to the spices, dairy products, and fruit juice, which can both enrich the taste of products, and improve the nutrition. Chitosan Oligosaccharidescan be applied in fruit and vegetable preservation because they keep the fruit and vegetable fresh.

3. Daily chemical industry

With its biological function diversity, Chitosan Oligosaccharides are widely used in daily chemical industry.

· Moisturizing products

·Sunscreen products

· Hair care

4. Feedstuff industry

Chitosan Oligosaccharides overcomes deficiencies of previous antibiotics, probiotics and enzyme preparation. Chitosan Oligosaccharidesare a good nature feed additive with low dosage, no residual and strong stability.

·Feed additive in animal husbandry: pig, cattle, chicken, etc.

·Feed additive in aquaculture: sea cucumber, abalone, shrimp, etc.

5. Veterinary medicineindustry

Antibacterialdiminish inflammation effect:prevent or treat the disease caused by Escherichia coli, Staphylococcus aureusSteptococcus mutans, etc.

Chitosan Oligosaccharidescan also strengthen immune system of the animals.

6. Agriculture

Chitosan Oligosaccharides can activate plant immune system, improve the disease resistance, promote cell activation, and stimulate plant growth.

As seed coating, soil conditioner and foliar spray reduce or remove fungal pathogens severity, to protect against microbial infections and soil fungus.
