Low temperature sterilization of egg using vaporized hydrogen peroxide

摘要

The present invention relates to a method for sterilizing spawned eggs with hydrogen peroxide vapor, the raw eggs are placed in a closed sterilization chamber without a washing process; A step in which hydrogen peroxide vapor sterilizes the egg surface and the inside of the sterilization chamber by injecting a certain amount of hydrogen peroxide into the steam state for a period of time inside the sterilization chamber; A post-treatment step for removing steam or condensed hydrogen peroxide remaining in the sterilization chamber after the sterilization process; Withdrawing sterilized eggs; The raw egg characterized in that it is configured is a sterilization method. The present invention provides a sterilization chamber in which sterilization of eggs is performed, a hydrogen peroxide steam generator supplied to the inside of the sterilization chamber, a circulation pump that supplies hydrogen peroxide vapor to the sterilization chamber and circulates air, and a sterilization chamber and a discharge pipe to remove hydrogen peroxide vapor after sterilization. It utilizes a sterilizer consisting of a dehumidifier connected through it. The method for sterilizing eggs according to the present invention can effectively sterilize bacteria, such as Salmonella and E. coli, which may exist on the egg surface by using hydrogen peroxide steam without washing the edible egg at a low temperature, and protect the cuticle layer on the egg surface. It is very effective in preventing bacterial infection and maintaining freshness and long-term storage.
