Chitin, a linked by β(1→4) bonds, is the main component in the cuticles of crustaceas, insects, and mollusks and in the cell walls of some microorganisms. In the nature, three different crystalline polymorphic forms of chitin exit under natural conditions. These forms differ in the packing and polarity of the N-acetylglucosamine chains. In this study, we were isolated from crab shell, squid pen, and beetles of cuticles by treatment with dilute NaOH solution for deprotenization, followed by treatment with dilute HCl solution for demineralization, and then analyzed by FT-IR, X-ray diffraction, Solid state 13C CP/MAS NMR, and DSC. And then chitin gel matrices were prepared using α,β,γ-chitin and dissolution characteristics were investigated.
