“…Decreasing of values was consistent during 6 month storage period which were 3.54 at the beginning and 0.00 log cfu/g at the end. The results were parallel with the results obtained by Nur et al [18] who reported the effect of ozone treatment on fungi counts leads a serious reduction. Allen et al and Wu et al also reported in their study that the gaseous ozone was very effective in the inactivation of fungi in the wheat [20] [21].…”

“…According to results the number of bacteria decreased from 4,93 to 3.87 log cfu/g in natural sample and from 4.51 to 3.10 log cfu/g for ozonated natural sample after six months of storage. The decrease may be due to several reasons, including the lack of adaptation of bacteria, sudden changes in the environment in which they live [18]. Another factor that causes the decrease in the number of bacteria may be the high storage temperatures in this study which were 24.7˚C to 34.8˚C.…”

In this study, ozone gas was applied to samples of durum wheat stored in four experimental groups (durum wheat without any treatment for comparison, durum wheat treated with ozone, purified durum wheat, and purified durum wheat treated with ozone). Two groups were treated with ozone gas at 3 ppm concentration for 1 hour. Groups were then placed in air-tight glass jars and stored for 6 months at variable temperatures between 24.7˚C to 34.8˚C. Microbiological (total count bacteria, yeast/molds and coliform) and physical properties (moisture, color and ash) evaluated. Ozone application statistically caused a significant reduction in the numbers of bacteria, yeast, molds and coliforms. Ozone application, washing process and storage temperature are the major factors affecting the microbial counts. No significant differences were determined in moisture and ash contents of samples after ozone treatment. The color measurement results showed that color values of wheat samples were affected by ozone treatment, storage and washing.

“…Experimental study on the current-voltage characteristics for atmospheric pressure DBD has been done by Pongsathon [14]. Nur et al produced ozone by using DBD plasma and it was implemented in the rice storage for maintaining the rice quality [15]. Figure 1 shows a series of experiments in this study.…”

This paper presents a characterization of an integrated ozone generator constructed by seven of reactors of Dielectric Barrier Discharge Plasma (DBDP). DBDP a has spiral-cylindrical configuration. Silence plasma produced ozone inside the DBDP reactor was generated by AC-HV with voltage up to 25 kV and maximum frequency of 23 kHz. As a source of ozone, dry air was pumped into the generator and controlled by valves system and a flowmeter. We found ozone concentration increased with the applied voltage, but in contrary, the concentration decreased with the flow rate of dry air. It was also found that a maximum concentration was 20 mg/L and ozone capacity of 48 g/h with an input power of 1.4 kW. Moreover, in this generator, IP efficiency of 8.13 g/kWh was obtained at input power 0.45 kW and air flow rate of 9 L/min. Therefore, be the higher ozone capacity can be produced with higher input power; however, it provided lower IP efficiency. The effect of dry air flow rate and applied voltage on ozone concentrations have been studied. At last, spiral wire copper was very corrosive done to the interaction with ozone, and it is necessary to do a research for finding the best metals as an active electrode inside of the quartz dielectric.
