“…The flow of the generated ozone was controlled using a cylinder flow regulator containing a flowmeter. The applied ozone dosage was calculated by multiplying the ozonation time with concentration and divided by the treatment chamber volume . Ozone was introduced into a cylindrical acrylic chamber, with an internal diameter of 12 cm and a height of 28 cm, containing 1 kg of wheat (Fig.…”

BACKGROUND Ozone is a highly oxidative gas that has a long history of safe use as a disinfectant and sanitizer from producers of pharmaceuticals and many other organic compounds. In the current work, disinfestation of stored wheat grain infested with a common insect, Rhyzopertha dominica, was attempted through ozone (O3) treatment as an alternative to chemical fumigants. RESULTS The optimized treatment conditions for ozone fumigation of stored wheat grain were 12% (w/w) grain moisture, 2.5 g m−3 ozone concentration and 8 h of treatment. The mortality of R. dominica adults, pupae, larvae and eggs was 97, 100, 99 and 100%, respectively. Moisture and protein content of the ozone‐treated wheat was found to be lower as compared to infested wheat. Microstructural changes in the treated samples were clearly visible on scanning electron microscopy images, whereas minimal changes at the molecular level and of rheological parameters were evident based on Fourier transform infrared spectroscopy peak and rheometry data. CONCLUSION Ozone was found to be an effective reagent for disinfestation, aimed at all life stages of R. dominica in stored wheat grain, that leaves no residue behind. Rotational strategies can be applied to obtain increased mortality while maintaining the usability of the grain for different purposes. © 2019 Society of Chemical Industry

“…Direct application of ozone for sterilization of food products has been accorded the GRAS (generally recognized as safe) status by FDA (). Ozone is widely being used as a potential disinfectant in the fruit juices (apple, peach and orange), food grains (rice, wheat and maize), dairy products (powdered milk, fluid milk and cheese), meat, poultry and water processing industries to control the fungal, microbial and enzyme activities (Pandiselvam, Subhashini et al, ; Pandiselvam, Sunoj, Manikantan, Kothakota, & Hebbar, ; Tiwari et al, ). Ozone can be generated on‐site using an ozone generator with oxygen concentrator making it an attractive alternative to the conventional fumigants (Pandiselvam, Chandrasekar, & Thirupathi, ).…”

Extending the storage life of legumes by protecting it from the Callosobruchus maculatus infestation is a major concern for the producers, processors and exporters. Legume processing industry requires “greener” alternatives to the conventional fumigants. Gaseous ozone has a great potential as an insect management strategy that is suited for this niche. Nevertheless, the efficacy of ozone against C. maculatus is yet unknown. A laboratory study was conducted to test the insecticidal effect of ozone in controlling the infestation of C. maculatus in green gram. We have determined the concentration of ozone exposure time–mortality relationship for all the stages of C. maculatus that were exposed to 500–1,500 ppmv ozone. The percentages of mortality for different stages of C. maculatus increased with the increase in ozone concentration and exposure time. It was documented that adult stage is least tolerant to ozone (500 ppmv for 274.40 min exposure required to kill 90%), whereas the most tolerant stage is pupa (500 ppmv for 1816.54 min is required to kill 90%). The results indicate that gaseous ozone is the attractive alternative to the synthetic fumigants.

An ab initio study, using the coupled cluster calculations (CCSD) method was conducted to investigate the kinetics of the ozone degradation in gas and aqueous phases considering the reaction of ozone with the hydroperoxyl radical. Two potential transition state paths, oxygen and hydrogen transfer, are studied and compared. It was revealed by the ab initio quantum chemical calculations that the calculated overall rate constant in the gas phase differs by approximately an order of magnitude from measured values. However, the calculated selectivity (branching fraction), which was measured directly with isotope studies of hydrogen atom transfer, is almost exactly equal to the experimental value at 298.15 K. The sensitivity analysis showed that adding the reaction between ozone and hydroperoxyl radical to the kinetic model accelerates the decomposition process by more than four times in the aqueous phase (pH = 7–8.5), and for an order of magnitude change in the rate constant of this reaction, the decomposition half‐life changes by 20–45 %. This result might affect our understanding of atmospheric ozone chemistry.
