nbsp;High-Voltage Electrical Discharges (HVED) are considered an emergent extraction technique based on the application of high-pulsed voltages. The aim of this chapter was to review its fundamentals for applications at laboratory and industrial scales. The configuration of devices and employed electrodes is described. Moreover, main steps required for using HVED and most important factors affecting this technique are also highlighted. Extraction of high added-value compounds from food waste and plant matrices using batch HVED has been the most usual application in last five years. In many cases, the low selectivity of the technique has made the use of a solid-liquid extraction step after HVED application necessary.
