Shredded tobacco plants or leaves are selected after harvesting and dried. They are irradiated with high energy electrons from an accelerator. Instantaneously, harmful protein-containing substances in the tobacco are destroyed, together with tobacco mosaic virus and other harmful substances. Simultaneously, formation and fixing of aromatic and pigmenting materials takes place. Alkaloids, harmful to health, are reduced. This obviates the lengthy fermentation process formerly used to treat virgin tobacco, which can foster undesirable biochemical side reactions and cause germ multiplication. Independent claim - Both the method and corresponding plant are claimed. Preferred features: A powerful electron accelerator (10 MeV) has an electron window, sealing against vacuum. The conveying system to the irradiation chamber passes through a climatic tunnel, in which tempered pure tobacco extract in vapor form acts on the tobacco passing through. Dried and shredded tobacco is irradiated by electrons in a heated, rotary, post-ripening vessel, and is aerated using oxygen.
