SPECIAL MOLECULAR WEIGHT CHITOSAN
The solubility of chitosan is related to the degree of deacetylation, relative molecular weight and viscosity. The higher the degree of deacetylation, the smaller the relative molecular weight and the more soluble in water. The lower the degree of deacetylation, the greater the relative molecular weight and viscosity. Chitosan has good adsorbability, film-forming ability, permeability, fibrinolytic ability, moisture absorption and moisture retention. The degree of deacetylation and viscosity (average molecular weight) are the two main properties of chitosan.
Special molecular weight chitosan is refined from high quality product and the range of molecular weights is from 20,000 to 300,000.Specifically,molecular weights are 300,000 , 250,000 , 200,000 , 150,000 , 100,000 , 50,000 and 20,000/This product is suitable for many applications in different fields and some indexes such as degree of deacetylation can be customized.
Deacetylation degree and other indicators can be produced according to customer demand.
Chitosan is tasteless, odorless and non-toxic. Pure chitosan has slightly pearl luster. The relative molecular weight of chitin in living organisms is 1×102-2×106, and after extraction, the relative molecular weight of chitin is about 3×105-7×105, and the relative molecular weight of chitosan prepared from chitin is even lower, about 2×105-5×105. The relative molecular weight of chitin and chitosan in the manufacturing process is usually expressed by the value of the viscosity.
Chitosan with a relative molecular weight of 10,000 has many excellent functions, such as inhibiting the growth of tumor cells, reducing cholesterol, blood sugar and blood lipids in serum and liver, enhancing immunity, strengthening liver function, promoting the generation of spleen antibodies, promoting the proliferation of bifidobacteria, inhibiting the growth of Escherichia coli, and moisture absorption and moisture retention.
