METHOD FOR STERILIZING SEALED AND PACKAGED FOOD USING ATMOSPHERIC-PRESSURE PLASMA, AND SEALED AND PACKAGED FOOD PREPARED THEREBY

摘要

The present invention relates to a method for sterilizing sealed and packaged food using atmospheric-pressure plasma, and sealed and packaged food prepared thereby. The method comprises the steps of: injecting a gas containing 10 vol% of oxygen, carbon dioxide or a mixture gas thereof into food for sealed packaging or vacuum packing said food with a plastic packaging material; and treating the packaged food with direct atmospheric-pressure plasma, thereby allowing food which cannot be heat treated, such as fresh food and the like, to be sterilized, and allowing food to be sterilized even if polyethylene, polypropylene, nylon, and polyethylene terephthalate through which plasma does not pass are used as a food packaging material.
