Chitosan is the only alkaline amino polysaccharide that exists in large quantities in natural polysaccharides. It has a series of special functional properties and has extensive and important application value in agriculture, food and other aspects. It has rich sources, simple preparation and film formation, and superior fresh-keeping performance. It will play an increasingly important role in food preservation, shelf life extension and other aspects.
Chitosan has the functions of enhancing human immunity, removing excess fat, inhibiting harmful bacteria, reducing blood lipids, regulating blood glucose, non-toxic anti-cancer effect and being used as biomedical materials. The research shows that chitosan can adsorb heavy metals such as cadmium, mercury and copper, and can be used as flocculating colloidal particles for juice clarification, sucrose purification, wastewater treatment, protein mycelia flocculation, etc.
Because chitosan has the advantages of biological function, safety, non-toxic, biodegradability and biocompatibility, it has a good application prospect in medicine.
In agriculture, chitosan is a very effective carrier of chemical fertilizers and pesticides, which can reduce the pollution of agricultural chemical fertilizers to the environment, effectively protect the environment and maintain ecological balance.
