Objective To optimize the process conditions of extracting pomelo peel oil by subcritical fluid extraction. Methods The extraction time, the ratio of material to liquid and the amount of entrainer were taken as the factors, the single factor and orthogonal experiments were carried out with the extraction rate of essential oil as the experimental index. Results The optimal process conditions for the extraction of pomelo peel oil by subcritical fluid technology were extraction time 40 min, ratio of material to liquid 1:7(m:V), entrainer addition amount 0.6 mL/g. Under these conditions, pomelo peel essential oils reached a maximum extraction rate of 1.35%. Conclusion Subcritical fluid extraction technology for extracting pomelo peel oil has a relatively high extraction rate.
