Recent advances in high voltage electric discharge extraction of bioactive ingredients from plant materials

Abstract

High voltage electric discharge (HVED) extraction is a novel, efficient, eco-friendly extraction technique, for which HVED is considered to be a probable alternative technique to conventional extraction methods. These years, HVED extraction has had a high-speed development and has been widely applied in the extraction of various bioactive compounds. This review aims to generalize the recent advances in the field of HVED extraction. An overview of different HVED extraction systems and devices including batch, continuous and circulating HVED extraction systems is involved in this review. In addition, the critical process factors, recent applications as well as advantages and disadvantages of HVED are also detailed. And the future trends of HVED are anticipated in the end of this article.
