为提高菜籽油的得率，探讨应用复合酶法提取菜籽油的最佳工艺条件。以挤压处理后的油菜籽为原料，提油率为考察指标，对复合酶种类和配比进行筛选后，在单因素试验基础上，通过响应面优化试验得出最佳酶解条件。结果表明：以中性蛋白酶、果胶酶和α-淀粉酶为复合酶组成，其配比为0.573∶0.315∶0.112；酶解最佳工艺条件为：酶解温度50 ℃、酶解时间4 h、酶解pH 6、料液比1∶4、复合酶添加量2%，在此条件下油菜籽清油的提油率可达92.333%。

In order to improve the oil extraction rate, the optimum process conditions of rapeseed oil extraction by complex enzyme method were discussed. The extruded rapeseed was used as raw material and the oil extraction rate was used as the index to choose the enzymes species and ratio. The enzymatic extraction conditions were optimized by single factor test and response surface optimization test. The results indicated that neutral protease, pectinase and amylase were selected as the suitable enzyme, and the appropriate proportions were 0.573:0.315:0...
