Abstract:

For a better development and ultilization of rabbit whiting produced in the spinning process of rabbit fiber,the rabbit whiting waste was tested by scanning electron microscopy (SEM),biuret test,sodium dodecyl sulfate polyacrylamide gel electropheresis (SDS-PAGE),fourier transform infrared spectroscopy,X-ray diffraction and differential scanning calorimetry (DSC) to characterize its apparent structure and composition. The experimental result prove that the rabbit whiting is from the surface exfoliate of rabbit hair,which the length,width and thickness are range of 20~50μm,2.0~6.0 μm and 0.4~0.7μm respectively. And keratin as the main composition with?molecular?weight?11kDa approximately. Therefore,rabbit whiting is regard as a good material for keratin extraction. The keratin was extracted from rabbit whiting further via sulphitolysis method,as a kind of anti-ultraviolet additive applied in cosmetic. The rabbiting whiting has better ultraviolet ray absorption than sunscreen products via UV test in the ultraviolet range of 200~320nm.

Key words: rabbit whiting, component structure, keratin, ultraviolet absorption
