Method of chitin production from chitin containing raw materials

摘要

Chitin and chitosan are produced by alkali treating of a chitin- containing fragmented raw material, which includes an electrochemical process in NaOH solution, with a constant electrical current source of 4- 11 A, a density of 0.05-0.2 A/cm2, a current of 15- 50 V, for 10-45 minutes, with the raw material and NaOH solution at a proportion of 1:1.5- 1:4 while the concentration of NaOH solution remains 0.15-2%.
