Investigation of Sterilization Effect for Overlapping Pieces in Non-Thermal Sterilization Method of Packaged Fresh Foods Using Pulsed Barrier Discharge

It is important to secure food safety. If a packaged can be sterilized, poisoning reduced considerably because the in plastic container useful prevent attaching microorganisms. However, fresh food, e.g., salad or sashimi, cannot sterilized by thermal sterilization. Therefore, we are studying sterilization methods for foods, such as packed salads. In this study, have investigated applicable probability of method using cold plasma applied food. Especially, microorganisms living small hollow between overlapped foods. A petri dish with lid was used simulating container. The into barrier discharge generated pulsed voltage. E. coli target set on culture agar medium instead salad. experimental results showed that combining film and voltage sterilize foods
