Chitosan Powder

What Is Chitosan Hydrochloride Powder?

Chitosan powder, the product of N-deacetylation of chitin, chitin, chitosan, and cellulose have similar chemical structures, cellulose is a hydroxyl group at the C2 position, and chitin and chitosan are at the C2 position Chitin and chitosan have many unique properties such as biodegradability, cell affinity and biological effect, especially chitosan containing free amino groups, which is the only natural polysaccharide alkaline polysaccharides.
The amino groups in the chitosan molecular structure are more reactive than the acetamido groups in the chitin molecule, making the polysaccharide have excellent biological functions and can undergo chemical modification reactions. Therefore, chitosan is considered as a functional biomaterial with greater application potential than cellulose.
Chitosan is the product of natural polysaccharide chitin with partial acetyl group removal. It has various physiological functions such as biodegradability, biocompatibility, non-toxicity, antibacterial, lipid-lowering, and immune enhancement. It is widely used in food additives, textiles, etc. , agriculture, environmental protection, beauty 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 treatment and pharmaceuticals Development and many other fields and other daily chemical industry.

What Are The Benefits?  

Antibacterial effect
Chitosan has a wide range of antibacterial effects, but different concentrations of chitosan have different antibacterial capabilities. For example, when the concentration of chitosan is 0.1%, it can completely inhibit the reproduction of various molds of the Fusarium genus within 8 days, but the concentration It has no effect on molds such as Rhizopus, Penicillium, and Aspergillus. When the concentration is 0.4%, it has a strong inhibitory effect on Escherichia coli, Proteus vulgaris, Bacillus subtilis and Staphylococcus aureus. In addition, chitosan with different degrees of deacylation has different antibacterial properties, and chitosan with a high degree of deacylation has strong anti-mold ability. One of the reasons is that chitosan interacts with the surface of fungal cells to increase the permeability of the cells. The antibacterial effect of chitosan, sodium acetate and adipic acid is more obvious without affecting the flavor of food.
The antibacterial effect of chitosan mainly has the following two mechanisms:
One is that chitosan forms a layer of polymer film by adsorbing on the cell surface to prevent the transport of nutrients into the cell, thereby playing an antibacterial and bactericidal effect;
Another mechanism is that chitosan penetrates into the cell body, adsorbs the cytoplasm with anions in the cell body, and flocculates, disturbing the normal physiological activities of cells, thereby killing bacteria. Because the cell wall structures of Gram-positive bacteria and Gram-negative bacteria are different, the two effects have different effects on them, so chitosan with different relative molecular weights has different antibacterial mechanisms.

Chitosan is a dietary fiber that has the functions of lowering serum cholesterol, regulating intestinal flora, and lowering blood pressure. After the human body ingests chitosan, stool analysis shows that it is hardly digested and absorbed, so it is a kind of dietary fiber. Studies have shown that chitosan has some properties of dietary fiber, such as water retention, swelling, adsorption and indigestible absorption, etc., can promote digestive tract peristalsis, absorb toxic substances, increase defecation volume, reduce abdominal pressure and intestinal pressure , Improve the occurrence of constipation, etc. The physical and chemical effects of chitosan and gastric mucin are similar, and it has the functions of inhibiting gastric acid, anti-gastric ulcer, and anti-inflammation. It is a polysaccharide resistant to gastric acid. A protective film can be formed in the stomach to reduce the irritation of gastric acid on the ulcer surface.

Application Direction

Chitosan has been discovered for more than 100 years, and many people are studying it, and it is widely used in agriculture, food, medical treatment, and industry.

Applications in the food industry
Chitosan can be used as a binder, humectant, clarifier, filler, emulsifier, glazing agent and thickening stabilizer in the food industry; as a functional oligosaccharide, it can lower cholesterol, improve the body's immunity, Enhance the body's anti-disease and anti-infection ability, especially has a strong anti-tumor effect. Because of its rich resources and high application value, it has been developed and used in large quantities. In industry, chitosan is extracted by enzymatic or acid hydrolysis of shrimp or crab shells.

Applications in daily chemistry
Chitosan is non-toxic, tasteless, and has antibacterial effect. When it is mixed into cosmetics, it can improve the film-forming property of the product, has antibacterial and moisturizing functions, and does not cause any allergic irritation. For example, introducing hydroxypropyl ammonium chloride group into chitosan molecule, the obtained chitosan hydroxypropyl trimethyl ammonium chloride can enhance the hydration ability of chitosan, improve its moisture absorption and moisturizing performance, and become a rich source , cosmetic moisturizing material with good performance. Various hair shampoos and hair care products made by adding chitosan have the effects of easy combing, fluffy hair, full hand feeling and bright hair color. Works best on fine hair that is prone to breakage and split ends. Hundreds of daily cosmetics containing chitosan have been sold in Europe, the United States, Japan and other countries and regions.

Applications in the pharmaceutical industry
The National Pharmacopoeia (Part Four) stipulates that chitosan can be used as pharmaceutical excipients, disintegrants, thickeners, etc.
