Pretreatment By Pulsed Electric Field For The Extraction Of The Microwave Assisted Essential Oil Of An Aromatic Plant

Abstract
This work concerns the extraction of the essential oil of a medicinal and aromatic plant peppermint by hydro distillation then by a pulsed electric field treatment and a hydro distillation assisted by microwave to study the parameters having an impact on the yield in the essential oil. In this work, we discussed the different bibliographic knowledge on pulsed electric field (PEF) treatment, microwave technology, essential oils and aromatic and medicinal plants.
