摘要

利用响应面法对姜精油的超临界萃取工艺进行优化。在单因素试验基础上选取试验因素与水平,根据中心组合(Box-Benhnken)试验设计原理采用三因素三水平的响应面分析法,依据回归分析确定各工艺条件的影响因素,以姜精油提取率为响应值作响应面分析。在分析各个因素的显著性和交互作用后,得出超临界萃取姜精油的最佳工艺条件为:萃取压力38MPa、萃取温度30℃、萃取时间110min,此工艺条件下的姜精油提取率为1.92%。

Abstract

Based on single factor tests,the optimum extraction conditions of oil from ginger essential was obtained through Box-Benhnken central combination design and RSM.The results showed that the optimum extracting conditions of polysaccharides were as follows:extraction pressure 38 MPa,extraction temperature 30℃,extraction time 110min.Under such conditions,the one-time extraction rate was up to 1.92%.

Key words： ginger essential oil; supercritical carbon dioxide extraction; response surface methodology
