Optimization of ultrasound system for the extraction of volatile compounds in Citrus junos (yuzu) peel using response surface methodology

The aim of this study was to study the optimum condition of ultrasound system for the extraction of volatile compounds in Citrus junos (yuzu) peel using response surface methodology in combination with a Box-Behnken experimental design. The effects of ultrasound amplitude (X1), sonication temperature (X2), and sonication time (X3) on the changes of volatile compounds were investigated. The response variables, such as the total peak area of volatile compounds (Y1) and the peak area of limonene (Y2), were obtained using gas chromatography-mass spectrometry. Based on the results,the predicted optimal extraction conditions for Y1 included an ultrasound amplitude of 65.56%, sonication temperature of 62.14℃, and sonication time of 57.85 min. The predicted optimization extraction conditions for Y2 were an ultrasound amplitude of 74.94%, sonication temperature of 64.12℃, and sonication time of 61.00 min. In conclusion, this study provided useful information on the ultrasound system, which is a non-thermal extraction method for volatile compounds.
