Problems solved by technology
[0004] At present, most of the extraction methods of bergamot essential oil are cold pressing, steam distillation and carbon dioxide supercritical extraction. The cold pressing method can guarantee the quality of the essential oil, but it is easy to cause organic solvent residues, and the risk of later use is higher
Carbon dioxide supercritical extraction method is expensive and the extraction cost is high
Steam distillation is widely used, but high temperature can easily damage the quality of essential oils

Embodiment 1
[0016] Embodiment 1, a kind of efficient extraction process of bergamot essential oil, carries out following steps successively:
[0017] 1) Fresh golden bergamot crushed:
[0018] Take the fresh golden bergamot fruit that has just been picked and crush it;
[0019] 2) Ultrasonic pretreatment
[0020] Take 100 g of pulverized bergamot samples and process them ultrasonically at 45 kHz for 30 min;
[0021] 4) steam distillation extraction
[0022] Take 100 g of the pretreated bergamot sample, add 200 mL of distilled water, and heat and reflux for extraction for 1 h.
[0023] The results showed that the yield of bergamot essential oil reached 2%, and the aroma of the obtained essential oil was basically preserved.
