摘　　要：稀土或植物单宁与胶原作用都不能使胶原有较高的热变性温度。本文研究中，将稀土和植物单宁结合与胶原作用获得了很好的协同效应，使胶原的热变性温度由５５℃上升到１０２℃。High thermal denaturating temperature can not be obtained with RE, or vegetable tannins acting on collagen protein. In this paper, strong synergistic effect was obtained when collagen protein was acted by RE and vegetable tannins at the same time, and the thermal denaturating termperature of collagen protein was increased from 55℃ to 102℃.
