摘　　要：使用200keV和10MeV电子加速器分别研究了电子束辐照对烟草中的烟草甲虫及细菌的杀灭效果以及对烟叶品质的影响。研究表明:通过电子束辐照可高效、快速实现烟叶内部所有菌虫的无害化,辐照后的烟叶在仓库验证中有良好的保持性,38 d内未检出任何菌落。辐照对烟叶的基本理化指标、有机酸含量及矿质元素含量无明显影响,过高能量会使烟叶中的新植二烯挥发损失,从589.91μg/g降至418.64μg/g,使其香气质量有一定程度降低。针对仓储烟叶的未来辐照实际应用,Fluka仿真结果表明,3MeV能量的电子束足以穿透现有烟叶堆积密度的整箱储运烟叶。The effects of 200 keV and 10 MeV electron-irradiation accelerators on the eradication of lasioderma serricorne and bacteria in tobacco and on the quality of tobacco leaf are investigated.By controlling the parameters of electron-beam irradiation,all lasioderma serricorne and bacteria inside tobacco can be eradicated efficiently and rapidly.The irradiated tobacco exhibits good retention based on a validation experiment,and no colonies are detected within 38 d.The irradiation has no significant effects on the basic physical and chemical indexes or the organic-acid and mineral-element contents of tobacco.Excessive energy levels reduce the volatilization loss of neophytadiene in tobacco from 589.91 to 418.64μg/g,which indicates that the aroma quality of the tobacco deteriorates to a certain extent.Fluka simulation results show that a 3 MeV electron beam is sufficient to penetrate a full box of stored tobacco at existing tobacco stacking densities.
