正交实验法与多元非线性回归法优化苏杏二陈糖浆水提工艺的比较分析

摘要

Objective To select optimum water extraction process of SuXingErChen Syrup by orthogonal test and multivariate nonlinear regression analysis.Methods Naringin was extracted by water, Used the naringin content and extraction rate of extractum as indexes.Based on the orthogonal test and multivariate nonlinear regression analysis to make sure the best way for extracting naringin from SuXingErChen Syrup.Results The optimal conditions of water extraction process was that the herbs were added seven times the amount of water without infiltration,extracted two times with 80 min each time,which was selected by multivariate nonlinear regression analysis.Conclusion The process of water extraction for the preferred Su XingErChen Syrup is exact, high effective and suitable for production needs.%目的 通过正交实验法与多元非线性回归法,筛选苏杏二陈糖浆的最佳水提工艺.方法 以柚皮苷含量和浸膏得率为指标,运用正交试验及多元非线性回归分析法优化提取条件.结果 运用多元非线性回归法可以得到苏杏二陈糖浆的最佳水提取工艺为:无需提前浸泡,加7倍量的水提取2次,每次80 min.结论 苏杏二陈糖浆水提工艺结果准确、高效,适合生产需求.
