Optimization of the Extraction Process of Tribute Citrus Essential Oil by Responsive Surface Method
The response surface method was used to optimize the process conditions for extracting Tribute citrus essential oil by steam distillation,the effects of extraction time,liquid-to-material ratio,NaCl addition amount and ultrasonic power on the yield of Tribute citrus essential oil were explored,and the optimal process conditions were determined.The results showed that the optimal extraction process was 1.6 h extraction time,32 mL·g-1 liquid-to-material ratio,1.8%NaCl addition,and the yield of Tribute citrus essential oil was 3.16%,having small difference to the model calculated value of 3.19%.It showed that the extraction process of Tribute citrus essential oil optimized by the response surface method was feasible.
