What’s Chitosan

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.

4.Clarifying agent for fruit juice

Used as food additives, beverage supplement,thickeners, preservatives fruits and vegetables, fruit juice clarifying agent, forming agent, adsorbent, and health food.

Agriculture Grade

1. In agriculture, chitosan is typically used as a natural seed treatment and plant growth enhancer, and as an ecologically friendly biopesticide substance that boosts the innate ability of plants to defend themselves against fungal infections.

2. As feed additives, can inhibit and kill the harmful bacterium, improve animals immunity.


Industrial Grade

1. Chitosan has good adsorption characteristics of heavy metal ion, applied in treatment of organic waste water, dye waste water, water purification and textile industry.

2. Chitosan can be also applied in paper-making industry, improving the dry and wet strength of paper and surface print ability.

Environmental protection field


Chitosan and its derivatives is a good flocculant for wastewater treatment and 

metal recovery from metalcontaining waste water; in textile field: as a mordant, 

health care fabric, sizing agents, printing and dying.
