Abstract: Pulsed electric field (PEF) is a new type of physical field processing technology, which has the advantages of short treatment time, low-energy consumption and eco-friendly. In recent years, pulsed electric field (PEF) has shown potential in the application of recycling active substances in agricultural product processing wastes. In this paper, the mechanism and advantages of pulsed electric field enhanced extraction are reviewed. In addition, the application progress of pulsed electric field technology in the recovery of bioactive substances in different types of processing wastes is classified and summarized in detail to provide reference and guidance for the high-value utilization of by-products in the processing of agricultural products.
