A review on recent development in non-conventional food sterilization technologies

Abstract Sterilization is one of the most effective food preservation methods. Thermal sterilization technologies have been widely employed in food industry since they are well developed and require low investment cost. Demands of consumers for higher quality and fresh tasting products are growing rapidly. Recently, non-conventional sterilization technologies have gained significant attention, since they have the potential to provide products with a better quality, fresh-like taste, and may require lower energy to operate. However, none of these technologies have been commercialized yet. This review addresses the efforts, which have been made in the literature to lower sterilization temperature using combination of thermal and one of the non-thermal processing technologies, such as high pressure, UV, pulsed light, ultrasonic, pulsed electric field, irradiation, and cold plasma.
