Application:
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 arti-ficial 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.
5.Agricultural field
As growth promoters, bio-pesticides, feed additives, seeds, etc.
6.Field of tobacco
Tobacco sheet used as adhesives, low-tar filter and so on.
