Chitosan Cas 9012-76-4

2. Product features:

Biocompatibility and biological activity: Chitosan has good biocompatibility and can be enzymatically decomposed into low molecular weight chitosan oligosaccharide in the human body, which is easy to absorb. At the same time, it also has a variety of biological activities, such as improving immunity, activating cells, preventing cancer, lowering blood lipids, lowering blood pressure, anti-aging, etc.
Environmental protection characteristics: In the field of environmental protection, chitosan can be used in sewage treatment, protein recovery and water purification, etc., contributing to environmental protection.
Film-forming properties: Chitosan cross-links with each other through hydrogen bonds to form a network structure, which can be made into a film with a porous structure. This film has broad application prospects in food preservation, pharmaceutical packaging and other fields.

3. Process characteristics:

Green production: Using shrimp and crab shells as raw materials, enzymatic hydrolysis technology is used to directly obtain chitosan oligosaccharide products, reducing acid and alkali emissions and achieving green production.
High purity: By optimizing the preparation process and equipment selection, the yield and purity of chitosan can be improved to meet the needs of different fields.

4. Production process:

The main raw materials for preparing chitosan are derived from aquatic shrimp shells and crab shells. Its main ingredients are calcium carbonate, protein and chitin. The process of preparing chitosan from shrimp and crab shells is actually a process of decalcification, protein removal, decolorization and deacetic acidification. At present, the methods for preparing chitosan at home and abroad include acid-base method, enzymatic method, oxidative degradation method and mechanical processing method. The acid-base method uses dilute hydrochloric acid to convert insoluble calcium carbonate into soluble calcium chloride and separates it with the solution, then uses dilute alkali to dissolve the protein, and then undergoes processes such as decolorization, water washing, and drying to obtain chitin. Through the deacetylation reaction, chitin can remove the acetate group in the molecule and transform it into chitosan.

5. Product Application:

Chitosan is the product of removing part of the acetyl group from the natural polysaccharide chitin. It has various physiological functions such as biodegradability, biocompatibility, non-toxicity, antibacterial, anti-cancer, lipid-lowering, immunity enhancement, etc., and is widely used in food. Additives, textiles, agriculture, environmental protection, beauty and health care, cosmetics, antibacterial agents, medical fibers, medical dressings, artificial tissue materials, drug sustained release materials, gene transduction vectors, biomedical fields, medical absorbable materials, tissue engineering carrier materials, Medical and drug development and many other fields and other daily chemical industries.

HealthCare:
Chitosan has the effects of improving immunity, activating cells, preventing cancer, lowering blood lipids, lowering blood pressure, anti-aging, etc., and can be used in the fields of medicine and health care. As a drug carrier, it can improve the stability and bioavailability of drugs.

cosmetic:
Chitosan has good moisture absorption, moisturizing, conditioning, antibacterial and other functions, and is suitable for moisturizers, shower gels, facial cleansers, mousses, creams, lotions, colloidal cosmetics, etc. It can effectively make up for the shortcomings of general chitosan and provide high-quality raw materials for the cosmetics industry.

Chemical industry:
Chitosan can be used as a raw material for functional materials and used to prepare membrane materials, carriers, adsorbents, fibers, etc., and has broad application prospects.

feed:
Chitosan can be used as a feed additive to promote the growth and health of animals. At the same time, shrimp shells and crab shells are rich in protein and trace elements, providing good nutritional value to animals.

agriculture:
Chitosan can be used as a plant nutritional growth promoter. In addition, it can also be used in fields such as fruit preservation and soil improvement to provide support for agricultural production.

In summary, chitosan, as a natural polymer compound, has a wide range of application fields and market demand. With the continuous advancement of science and technology and the continuous development of the market, the production process and application fields of chitosan will continue to be optimized and expanded.
