Collagen protein was extracted from cowhide leather solid waste with chromium by hydrolysis of alkaline and cycle method. Then different molecular weight ranges of collagen protein were got by ultrafiltration. Collagen protein was characterized by High Performance Liquid Chromatography (HPLC) and Multi-angle Laser Scattering meter and the average molecular weight was got, based on that the average molecular structure model was established. The study will provide the theory basis for the modification research of collagen.
