Abstract
A system for treating food, the system including: a direct barrier discharge system including a pair of electrodes separated by a gap of at least 0.5 cm, wherein the direct barrier discharge system is configured to provide a feed gas between the electrodes, wherein the feed gas includes nitrogen and water, wherein a content of nitrogen in the feed gas is at least 75 vol % based on a total volume of the feed gas, and a relative humidity of the feed gas is at least 50% RH, wherein a content of oxygen in the feed gas is less than 1.5 vol % based on a total volume of the feed gas, and wherein the direct barrier discharge system is configured to provide an electric potential between the electrodes to generate a working gas having an ozone content of less than 20 ppm, based on a total volume of the working gas.
