Chitosan Usage and Synthesis.

Chitosan has a wide range of antibacterial effects, but the antibacterial ability of chitosan at different concentrations is different. For example, when the chitosan concentration is 0.1%, the reproduction of various molds of the genus Fusarium can be completely inhibited within 8 days, but this concentration has no effect on molds such as Rhizopus, Penicillium, and Aspergillus.

At a concentration of 0.4%, it has a strong inhibitory effect on Escherichia coli, Proteus vulgaris, Bacillus subtilis, and Staphylococcus aureus.

In addition, chitosans with different degrees of deacylation have different antibacterial properties, and those with a high degree of deacylation have strong antibacterial power. One of the reasons is that chitosan reacts with the surface of mold cells, increasing cell permeability. The preservative made of chitosan, sodium acetate, and adipic acid has a more obvious antibacterial effect and does not affect the flavor of food.

Uses of Chitosan.

It is mainly used in food, medicine, agricultural seeds, daily chemicals, industrial wastewater treatment and other industries. Chitosan oligosaccharides have the functions of improving immunity, activating cells, preventing cancer, lowering blood lipids, lowering blood pressure, anti-aging, regulating the body environment, etc., and can be used in medicine, health care, and food fields. In the field of environmental protection, chitosan can be used for sewage treatment, protein recovery, water purification, etc. In the field of functional materials, chitosan can be used for membrane materials, carriers, adsorbents, fibers, medical materials, etc. In the field of textiles, chitosan can be used for fabric finishing, health underwear, papermaking aids, etc. In the agricultural field, it can be used for feed addition, seed treatment, soil improvement, fruit preservation, etc. In the field of tobacco, chitosan is a good-performance tobacco sheet glue, and it has the characteristics of improving taste, burning non-toxic and odorless. Chitosan is a biocompatible, antibacterial and biodegradable polyelectrolyte with a wide range of biomedical and industrial uses. Its chemical properties and low toxicity can be used as a component of drugs, used in gene transfer systems, used as biodegradable membranes, and as a skeleton in tissue engineering.

Pharmacological effect of Chitosan.

Prodct Method of Chitosan.

20 g of chitosan was added into 300 mL of 50% NaOH solution, and after being completely soaked, it was heated at 95°C for 1.5 h, the alkali solution was filtered off, and the solution was washed with water until neutral, and dried at low temperature to obtain 15.6 g of colorless and transparent flaky product.
