A system and method for preserving stored foods. The system and method utilizes an apparatus for generating ozone and other atoms and molecules resulting from the bombardment of a feed gas with electrons having, preferably, a first electrode positioned within a channel in a second electrode. The first electrode is a substantially sealed tube made of dielectric material, having at least one electron gun positioned proximate an end for firing electrons into the first electrode. In electrical communication with the electron gun is a rod, maintained in a tube also made of dielectric material, which acts to maintain a constant energy level through the length of the rod and thus the length of the electrode. Within the first electrode is an inert gas which, upon the firing of the electron gun, is formed into a plasma. When a feed gas (generally air) is passed between the first and second electrodes, the electrons and plasma cause the formation of ozone and other atoms and molecules in the feed gas, which products have beneficial uses in the preservation of stored foods. The treated feed gas is then passed into a permanent or mobile food storage unit, such as a potato storage facility, having an appropriate temperature and humidity level, to achieve a sufficient concentration and for a sufficient period of time to be beneficial.
