Specifications
Chitin (chitin) is first by the French study of the history of natural science, black professor (h. Bracolmot) found in mushrooms, in 1811 and named Fungine. In 1823, another French
scientists from Mr Gill crustacean insect elytra isolated from the same material, and named the chitin; In 1859, French scientists c. Rouget chitin soaking in concentrated KOH solution,
boil for a period of time, after wash out and found that it can be dissolved in organic acid; In 1894, the germans Ledderhose confirm Rouget modification of chitin is off part of the
preparation of acetyl chitin, and named as Nonoxynol 9 Factory chitosan,
namely chitosan
manufacturers; In 1939, Haworth won an uncontested synthesis method, to determine the structure of chitin; In 1936, americans Rigby won a series of authorized patents of chitin/chitosan
manufacturers, describes the separation of chitin from shrimp shell, crab shell, the method of preparation of chitin and chitin derivatives, the method of preparation of chitosan membrane
and chitosan solution, chitosan manufacturers manufacturers fiber method; In 1963, Budall proposed chitin there are three kinds of crystal shape; In the 1970 s, the research of chitin
increase; 80-90 - s of the 20th century, the research of chitin/chitosan manufacturers into the golden age.
The nature of this product and its related properties of polyelectrolyte and chitosan. The existence of a large number of amino allows manufacturers of chitosan react with anionic system,
so the two substances share will cause Theobromine Powder the
change of the
physical and chemical properties. Manufacturers of chitosan as a solution is to store and use, should be in the acidic environment, but as a result of the existence of acetal structure,
make its degraded in acid solution, the solution viscosity drops. If adding ethanol, methanol, acetone, etc can delay manufacturers of chitosan solution viscosity is reduced, the greatest
role in ethanol. Manufacturers and acetyl chitin, chitosan soluble chitin, glucosamine, for the kind of white powder, odourless, tasteless. This product is slightly soluble in water, hardly
soluble in ethanol. This product is a kind of cationic polyamine, in the pH < 6.5 high charge density (and therefore can be adsorbed on the anion surface and can chelate with metal ions).
This product is a kind of linear polyelectrolyte with active hydroxy and amino (chemical reactions can be performed and salt).
Pure chitosan manufacturer for white or gray translucent flake solid, it is soluble in dilute acid sticky stiff, chitosan in the dilute acid manufacturer of beta 1, 4 - glycosidic bond will
slowly hydrolysis, generate manufacturer of low molecular weight chitosan. Soluble in acid solution to form positively charged cationic groups. Manufacturers of chitosan in solution is more
positively charged polyelectrolyte, has a Heme Iron
Polypeptide strong
adsorption. Manufacturers of chitosan molecules containing amino with alkaline, under the condition of hydrochloric acid in gastric juice can produce ammonium salt, can make the intestinal
pH into alkaline, improve acid constitution. Chitin has a strong affinity to the cells of our bodies, into the chitin is broken down into basic units in the human body. The existence of
glucosamine in the human body. And acetyl glucosamine is the basic composition unit of hyaluronic acid in the body. So manufacturers of chitin and chitosan has good affinity to human cells,
no rejection.
