摘　　要：用酸提取法从鲫鱼中提取胶原蛋白，用不同浓度的盐酸作为脱钙溶液，以0.5 mol／L乙酸—乙酸钠缓冲溶液提取其胶原蛋白。单因素分析与正交试验结果表明：提取温度为6～10℃时，最佳提取条件为固液比1砄20，提取时间每次1.5 h，脱钙酸浓度为0.5 mol／L，脱钙时间3 h，胶原蛋白提取率为0.773％。Using hydrochloric acid with different concentrations as decalcification solution and the mixture of acetic and sodium acetate as buffer solution , the collagen wan extracted from erucian fish scale.The univariate analysis and orthogonal test results showed that the extraction ratio was 0.773% under the optimal conditions： the ratio of solid to solvent as 1：20, the extracting time as 1.5 days, the concentration of hydrochloric acid for decalcification as 0.5 mol/L and the decalcification times as 3 h.
