超声波辅助法提取生姜油的工艺研究

Study on ultrasonic wave auxiliary extraction technology of ginger oil

采用单因素和正交试验,进行了超声波辅助提取生姜油的工艺研究,得到最佳提取工艺条件。结果表明,选用体积浓度80%乙醇作为萃取溶剂,在超声时间35min,超声温度60℃,料液比1g:50mL,超声功率135W时提取效果最佳,生姜油最高得率为11.82%。在最佳条件下连续进行3次提取,累计得率可达12.91%。

In this study,ultrasonic assisted extraction of ginger oil was studied by single factor and Ortho-gonal test,and the optimum extraction conditions were obtained.The results showed that the best extraction effect and the highest yield of ginger oil were 11.82%at ultrasonic time of 35min,ultrasonic temperature of 60℃,solid-liquid ratio of 1g:50mL and ultrasonic power of 135W.Under the optimal conditions,the cumulative yield reached 12.91%after 3 times of extraction.
