Chitosan Oligosaccharide

 

Chitosan oligosaccharide is a low molecular weight oligosaccharide composed of 2 to 20 glucosamines connected by β-1,4 glycosidic bonds. It is a degradation product of chitosan.

 

It has a small molecular weight, usually less than 3 kDa, high water solubility, and strong biological activity, so it can be widely used in medicine, food, agriculture and other fields.

1. Enhance immunity
It can activate immune cells such as macrophages and NK cells, regulate Th1/Th2 immune balance, and assist in anti-virus and anti-tumor.

 

2. Antioxidant
It can remove free radicals, reduce oxidative damage, and protect skin collagen.

 

3. Regulate the intestine
Chitosan oligosaccharide can promote the proliferation of probiotics, inhibit harmful bacteria, and improve intestinal barrier function.

 

4. Lower blood lipids and blood sugar
It can inhibit fat absorption, lower cholesterol, improve insulin sensitivity, and assist in sugar control.

 

5. Promote wound healing
It has a good antibacterial effect, and can stimulate fibroblast proliferation, accelerate tissue repair, and can be used in medical dressings.

 

 

Feature	Chitosan Oligosaccharide	Chitosan
Molecular weight	Low, <3 kDa	High, usually >50 kDa
Solubility	Soluble in water and neutral pH solution	Soluble only in acidic solution
Absorbency	Directly absorbed in the intestine, high bioavailability	It can only be absorbed after enzymatic hydrolysis, and the utilization rate is low
Application	Medicine, functional food, cosmetics	Industrial adsorbents, sustained-release drug carriers, agriculture
Activity strength	Antioxidant, immune regulation	Such as film-forming and adsorption properties are stronger

 

Other:

 

(1) Preparation method: Chitosan is degraded into chitosan oligosaccharides by chemical method (acid hydrolysis), enzymatic method or physical method (ultrasound).

(2) Safety: Both are non-toxic, but COS are easier to metabolize due to their small molecular weight and have fewer side effects.

(3) Synergistic application: Chitosan is used as a carrier to encapsulate chitosan oligosaccharide powder, which can prolong their sustained release effect.
