Chitosan is a linear polysaccharide composed of randomly distributed β-(1-4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). It is made by treating shrimp and other crustacean shells with the alkali sodium hydroxide.

Chitosan has a number of commercial and possible biomedical uses. It can be used in agriculture as a seed treatment and biopesticide, helping plants to fight off fungal infections. In winemaking it can be used as a fining agent, also helping to prevent spoilage. In industry, it can be used in a self-healing polyurethane paint coating. In medicine, it may be useful in bandages to reduce bleeding and as an antibacterial agent; it can also be used to help deliver drugs through the skin.

More controversially, chitosan has been asserted to have use in limiting fat absorption, which would make it useful for dieting, but there is evidence against this.

Other uses of chitosan that have been researched include use as a soluble dietary fiber.

1. Promoting blood coagulation and wound healing;

2. Used as drug sustained-release matrix;

3. Used in artificial tissues and organs;

4. Improving the immunity, guarding against hypertension, regulating blood sugar, anti-ageing, enhancing acid constitution,etc.

1. Food Field
Used as food additives, thickeners, preservatives fruits and vegetables,fruit juice clarifying agent, forming agent, adsorbent, and health food.

2. Medicine, Health Care Products Field
As the chitosan non-toxic,has anti-bacterial, anti-inflammatory, hemostatic, and immune function, can be used as artificial skin, self-absorption of surgical sutures, medical dressing Branch, bone, tissue engineering scaffolds, enhance liver function, improve digestive function, blood fat, lowering blood sugar, inhibiting tumor metastasis, and adsorption and complexation of heavy metals and can be excreted, and so on, was vigorously applied to health food and drug additives.

3. Environmental Protection Field
Chitosan and its derivatives is a good flocculant for wastewater treatment and metal recovery from metal-containing waste water; in textile field: as a mordant, health care fabric, sizing agents, printing and dyeing.

4. Agricultural Field
As growth promoters, bio-pesticides, feed additives, seeds, etc.

Our Recommendation

(1) We can supply high-purity chitosan with deacetylation degree >95%.
(2) The viscosity is determined at 20°C with 1°C chitosan in 1°C acetic acid.The different applications of chitosan demand different type of chitosan, We can supply it according to the needs.
We can provide special molecular weight Chi Chitosan (20,000-300,000) and Chitosan Oligosaccharide (1,000-8,000). If you have any question, welcome to contact with us at any time.
