The food industry and consumers have significant interest in nonthermal pasteurization processes because they offer better quality and nutrition retention and are more energy efficient than traditional thermal processes. Non-thermal processes may also create value-added products and open new market opportunities. This chapter will provide an overview of several non-thermal processes with the potential for producing valued-added foods, including pulse electric field (PEF), high hydrostatic pressure (HHP), ionizing irradiation, UV light, non-thermal plasma (NTP), and concentrated high intensity electric field (CHIEF). Their respective mechanisms for inactivating microorganisms, technical characteristics, and current status of the application of these processes will be discussed.
