正交实验优选乌梅-木瓜饮提取工艺研究

Study on Optimum Extraction Technology of Mume Fructus and Chaenomelis Fructus by Orthogonal Experiment

基于L_(9)(3^(4))正交实验设计,采用醇提法,以提取时间、乙醇浓度、料液比为考察因素,以枸橼酸、齐墩果酸的含量以及干膏率为优选评价指标,优选出乌梅-木瓜饮的最佳提取工艺。最佳提取工艺为提取时间0.5 h,料液比为1:5,乙醇浓度为90%。实验结果表明,优选的提取工艺稳定可行,且提取效率较高,此提取工艺研究为乌梅-木瓜复合饮料的研发提供研究基础。

To optimize the extraction process of mume fructus-chaenomelis fructus decoction.Based on the L_(9)(3^(4))orthogonal experiment design,adopts the alcohol extraction method,takes extraction time,ethanol concentration,material-to-liquid ratio as the inspection factors,and takes the content of citric acid and oleanolic acid and dry paste as the preferred evaluation indicators.Optimizing the best extraction process of ebony-papaya drink.The best extraction process is 0.5 h,the ratio of material to liquid is 1:5,and the concentration of ethanol is 90%.The experimental results show that the optimal extraction process is stable and feasible,and the extraction efficiency is high.This extraction process research provides a research basis for the research and development of ebony composite beverage.
