Abstract

Apple Mango has been a representative product in Miyazaki. However, fruit rot disease such as Stem - end Rot and Anthrax Pathogen is serious. Therefore, it is necessary to perform sterilization. So, we fabricated a plasma sterilization device using He and O2 gas at atmospheric pressure. In order to confirm the usefulness of the source, we measured optical emission intensity of plasma and we performed sterilization for Bacillus Subtilis. As a result, it was confirmed the sterilization effect and a best mixing rate of O2 gas.
