亚临界提取罗勒油工艺研究

Study on Subcritical Extraction of Basil Oil

主要研究探讨亚临界提取罗勒油的工艺参数,分别进行了单因素试验及正交试验确定其最优提取条件,结果表明:罗勒油的最佳提取工艺条件是大豆油与罗勒叶质量比为1︰3、萃取温度为65℃、萃取时间为65 min、萃取次数为3次,在此条件下罗勒的出油率为5.83%。

In this paper,the process parameters of subcritical extraction of basil oil were studied.The optimal extraction conditions were determined by single factor and orthogonal experiments.The experimental results showed that the optimal extraction condition of basil oil was as follows:the mass ratio of soybean oil to basil leaves was 1/3,the extraction temperature was 65℃,the extraction time was 65 min,and the frequency of extraction was 3 times.Under this condition,the oil yield of basil was 5.83%.
