Chitosan is a product of N-deacetylation of chitin, which has a similar chemical structure to chitin and cellulose. Chitosan is widely used in various fields because of its unique biodegradability, cell affinity and biological effects.
In the field of medicine, chitosan has a variety of effects. First of all, the active free amino group in its chemical structure helps to improve the acidic constitution, strengthen the immune function of the human body, and eliminate harmful substances in the body. Chitosan can also be used as a drug carrier to stabilize drug ingredients, promote drug absorption, and help drugs reach target organs. In addition, chitosan can also be made into microspheres, which has good adhesion and is suitable for oral, nasal, gastrointestinal and other mucosal drug delivery, and the surface can be connected with functional groups to flexibly load different drugs.
In the field of light industry, the solubility and film-forming properties of chitosan make it an ideal choice for the preparation of new fabric finishing agents. This finishing agent is truly formaldehyde-free, providing an environmentally friendly alternative for the textile industry.
In the field of environmental protection, chitosan can interact with glutaraldehyde for the treatment of industrial wastewater and the extraction of heavy metals, contributing to environmental protection.
In the field of life, chitosan is often added to cosmetics because of its non-toxic, tasteless and antibacterial properties to provide antibacterial and moisturizing functions. At the same time, chitosan also has a good moisturizing effect, which can improve the dry and rough skin, and make the skin smoother and more elastic.
In the field of agriculture, chitosan has a synergistic effect on pesticides and chemical fertilizers, which can improve the growth rate and yield of crops. In addition, chitosan can also activate plant cells, promote the growth of plant roots, increase the compressive strength of the cell wall, and facilitate the absorption and utilization of nutrients by plants.
In the food industry, chitosan can be used as a preservative to extend the shelf life of food due to its strong antibacterial and antioxidant properties. It can also be used as an edible antibacterial packaging material to provide a protective barrier for food and ensure the sensory and nutritional quality of food.
In general, chitosan plays an important role in many fields such as medicine, light industry, environmental protection, life, agriculture and food due to its unique biological activity and versatility. With the deepening of research and technological progress, the application field of chitosan will continue to expand.
