摘  要:
以林蛙皮为原料,研究其胶原蛋白的酸法提取工艺条件,通过单因素试验及Design Expert软件分析预测,根据生产实际优化调整提取胶原蛋白最优工艺条件为:料液比1∶18,盐酸浓度为0.16mol/L,浸提时间为5h,胶原蛋白提取最大量为28.20%。同时,对林蛙皮胶原蛋白产品进行傅立叶红外转换扫描图谱显示,通过酸法提取的胶原蛋白保存有比较完整的螺旋结构。DSC差热扫描得到酸溶胶原的变性温度为52.4℃,高于猪皮和牛皮胶原的变性温度37℃。

摘  要:
This thesis is to extract collagen from the remaining Rana chensinensis skin,and to study the collagen by acid extraction and enzymatic extraction process.Through analyzing and forecasting by the single-factor test and Design Expert software,according to the actual,the optimum process condition of products are:solid-liquid ratio 1∶18,hydrochloric acid concentration of 0.16mol/L,extraction time of 5h,the maximum amount of collagen extraction was 28.2%.Fourier transformation infrared scan patterns showed that acid extraction of the products,the experiments proved the system to take the acid-soluble collagen is the preservation of the original spiral structure completely.DSC scanning results showed that the acid-soluble collagen of original protein denaturation temperature is 52.4℃,which is more than the skin and cowhide collagen denaturation temperature of 37℃.
