Applications:

1 .  Flocculating agent

Chitosan and its derivatives is a good flocculant for wastewater treatment and metal recovery from metal-containing waste water; 

Also Juice defecation, flocculating of wine, sewage disposal,herbal medicine clarification and macromolecular substance recycle and so on.

2.Fresh-keeping Chitosan

Fresh-keeping chitosan has passed numerous times of testing experiments and practical experiments.For its excellent performance in pellicle forming and bacterial inhibition,chitosan is used for fresh keeping and preservation for fruits and vegetables.

3. Food Field

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

4 . 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.in textile field: as a mordant, health care fabric, sizing agents, printing and dyeing.
