Abstract
The essential oils and their volatile components have been widely used in cosmetic, food and medical industry, agriculture and food preservation fields. At present, the essential oils are mainly separated by fractional distillation. It has some drawbacks such as high-cost, high-energy consumption and could damage the thermolabile compounds. Therefore, its applications are greatly limited. The pervaporation (PV) is a newly emerging membrane-based technology and can effectively separate the thermolabile compounds environment-friendly with advantages of low-energy consumption and easy-operations. As a result, the PV holds great potential in separation of essential oils and fine-preparations of their components. In this paper, the recent research progresses of PV technologies used in essential oils separation were systematically summarized and the membrane materials, separation procedures and the present applicable situations of PV were also analyzed. The challenges of using PV in large-scale separation of essential oils were also been discussed and prospected.
