Product Description

What is Chitosan Powder?
 

Chitosan is derived from natural chitin by deacetylation. Chitosan containing free amino group is the only basic polysaccharide among natural polysaccharides. It has good biocompatibility and unique physical and chemical properties.

Chitosan  also known as deacetylated chitin, soluble chitin, polyglucosamine. It is white or off-white, slightly pearly luster, translucent amorphous solid, decomposed at about 185 ° C, insoluble in water and dilute alkali solution, soluble in dilute organic acids and some inorganic acids such as hydrochloric acid, but insoluble in dilute sulfuric acid, dilute nitric acid, dilute phosphoric acid, oxalic acid, etc. Chitosan contains both hydroxyl group and amino group, which can be used to form various derivatives with different structures and properties through acylation, carboxylation, hydroxylation, cyanation, etheration, alkylation, esterification, aldehyde imide, azide, salting, chelating, hydrolysis, oxidation, halogenation, grafting and crosslinking.

Chitosan can be prepared by deacetylation of chitin. It is usually soaked in 45%-50% sodium hydroxide solution and heated to 105ºC, kept warm for 2h, washed to neutral, pumped and filtered, and dried to obtain white chitosan with a slight pearl luster. The concentration of lye, reaction temperature and reaction time were the main factors affecting the properties of chitosan. In addition, the yield of chitosan prepared from different raw materials by the same method under the same conditions is also different. Relatively speaking, crayfish shell and sea crab shell are the preferred raw materials. In addition, chitosan can also be prepared by enzymatic method and microwave method, especially chitosan extraction by microorganism combined with biotechnology. Because this method is not affected by the seasonality of raw materials, the development prospect is promising.

The benefits of our Chitosan Powder

The effects of chitosan on disease prevention and health care include: strengthening immune function; Lower cholesterol; Lowering blood pressure, lowering blood sugar, strengthening liver function; Make blood vessels dilate, thereby improving the symptoms of back pain; Treat burns, scalds, accelerate the healing of wounds; Prevent gastric ulcers, absorb harmful substances in the body and expel them from the body.

 

Regulating hypertension: Chitosan is a positively charged cationic animal cellulose, which can absorb negatively charged chloride ions to prevent vasoconstriction and blood pressure increase caused by the increase of chloride ions; At the same time, it can effectively remove the fat deposits on the surface of the blood vessel wall, remove the root cause of blood vessel stenosis, and fundamentally regulate hypertension.

 

Lowering blood lipids: The positive charge of alkaline amino group in chitosan with hyperlipidemia and cardiovascular and cerebrovascular disease builds a barrier around negatively charged fat, and fat oil droplets cannot be digested and absorbed by the body, but are discharged from the body; The effective binding of chitin and bile acids prevents the absorb

 

Prevent bone calcium loss: Chitosan and osteoarthropathy Chitin is the main element in the manufacture of proteoglycan, and proteoglycan is the main component of osteoarticular cartilage. Supplementing chitin can promote the synthesis of proteoglycan, so as to effectively repair joints, promote the secretion of joint lubrication fluid, make periosteal fluid thicker and more viscous, thus strengthening the protective function of periosteal and reducing the friction and pain between joints. Chitosan can be deposited on the surface of bone, enhance the toughness of bone cortex, improve the elasticity of bone, make bone not easy to break, and effectively prevent the loss of bone calcium

The application of Chitosan Powder
 

Chitosan is the product of natural polysaccharide chitin, which has biodegradability, biocompatibility, non-toxicity, antibacterial, anticancer, lipid-lowering, immune enhancement and other physiological functions. It is widely used in food additives, textile, agriculture, environmental protection, beauty and health care, cosmetics, antibacterial agents, medical fibers, medical dressings, artificial tissue materials, drug slow release materials, gene transduction carriers, biomedical fields, medical absorbable materials, tissue engineering carrier materials, medical treatment and drug development
