CD concentrations & air method for food produce fumigation ~Selective Micro Technologies
"...Though the perchlorate ion has been identified as a degradation product in the treatment of fruits and vegetables with gaseous ClO2, Smith et al. confirmed “in the presence of a chlorine dioxide sink and in the absence of light, perchlorate formation from chlorine dioxide is nil” and “the formation of chlorate and perchlorate can be minimized or essentially eliminated ... if chlorine dioxide sanitation processes are protected from light” "As it comes into contact with food surfaces, chlorine dioxide gas will be consumed by the oxidation of organic matter and micro-organisms present on food. Unlike chlorine dioxide gas in-solution, which decomposes into various oxychloro species upon its exposure to water, gaseous chlorine dioxide will decompose into only chlorine and oxygen when released to the atmosphere." "In-line with the results of Lee, we conservatively estimate that the residual chlorite concentration is approximately 70% of chlorine dioxide consumed in-reaction and that residual chlorate concentration is approximately 15% of chlorine dioxide consumed in-reaction. The reaction’s remaining 15% can be categorized as minor reaction products." "Chlorine, however, will rapidly be broken down in reactions with ultraviolet light or other atmospheric particles to form the chloride particle. "
