目的:建立松籽油中γ-亚麻酸的提取工艺。方法:采取正交试验,将试验数据经直观分析和多元线性回归分析比较优选松籽油中γ-亚麻酸的提取工艺条件。结果:将试验数据结果进行两种处理方式得到了不同的优化提取工艺条件。结论:使用多元线性回归计算试验结果,可弥补正交极差方差计算不足,更有利于结果解释和工艺条件的优化。
Objective: To establish the extraction process of γ-linolenic acid in pine nut oil. Methods: Orthogonal test was adopted. The experimental data were analyzed by visual analysis and multiple linear regression analysis to compare the extraction conditions of γ-linolenic acid in pine nut oil. RESULTS: Two different treatment methods were used to obtain the optimum extraction process conditions. Conclusion: Using multiple linear regression to calculate the test results can compensate for the lack of calculation of the orthogonal range error, which is more conducive to the interpretation of results and the optimization of process conditions.
