Chitosan Oligosaccharide

Chitosan oligosaccharides use snow crab shells as the basic raw materials, which is prepared into chitosan by extraction and then degraded by biological enzyme technology. The degree of polymerization is between 2 and 20. It is combined with β-1, 4 of Glucosamine, with small molecular weight, good water solubility, high activity, and quickly absorbed by the human body. Chitosan is the only positively charged basic sugar in nature and has very unique biological functions.

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 aureus, Steptococcus 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.
