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%。
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%.
