Intensification of Essential Oil Extraction of Artemisia herba alba Using Pulsed Electric Field

摘要

In Algeria, the essential oils market is very modest and the development of this sector remains a problem to be solved. Artemisia herba alba (white wormwood) is aromatic and medicinal plant rich in essential oils. It is in great demand by the national and international industrial sectors: pharmaceutical, food, cosmetics ...). The extraction by conventional hydrodistillation gives low yield, a solution presented in this article is to make a pulsed electric field treatment to intensify the extraction of essential oils. The results indicate a good influence of the PEF on the efficiency of HE with reduction of the extraction time. The extraction yields obtained, for example being 2.05% for only 30 min of distillation after treatment with PEF (3kV/cm, n = 100) is 03 times more than a traditional extraction. This result will undoubtedly have a major socio-economic impact.
