Atmospheric pressure cold plasma technology has great application potential in the field of food safety. A novel atmospheric air dielectric barrier discharge device has been designed to generate plasma directly on the surface of spherical fruit. This device consists of the quartz tube, the high-voltage electrode attached to the outer wall of the quartz tube, and the fruit placed onto the inner surface of the quartz tube, acting as the ground electrode. The intensified charge-coupled detector images show that a uniformly scanning discharge channel is formed between the surface of treated substance and the inner wall of quartz tube. When the treated substance is rolled in the device, the uniform plasma is directly formed over the fruit surface. The bactericidal efficiency of plasma against pathogenic microorganisms on rolling fruit surface has been studied. The number of Staphylococcus aureus ( S. aureus ) on the surface of fruit treated by plasma for 15 s in rolling s...

大气压空气介质阻挡放电系统控制滚动果实表面的病原细菌

大气压冷等离子体技术在食品安全领域具有巨大的应用潜力。设计了一种新颖的大气介电屏障放电装置，以直接在球形水果的表面上产生等离子体。该设备由石英管，连接到石英管外壁的高压电极以及放置在石英管内表面上的作为接地电极的水果组成。增强的电荷耦合检测器图像显示，在被处理物质的表面与石英管内壁之间形成了均匀扫描的放电通道。当处理过的物质在设备中滚动时，均匀的血浆直接形成在水果表面上。研究了血浆对滚动果实表面的病原微生物的杀菌效率。滚动等离子体处理15 s水果表面金黄色葡萄球菌（S. aureus）的数量。
