| Abstract: |
| Atmospheric pressure cold plasma as an emerging technology is effectively used to inactivate microorganisms, pathogens and improve food safety. In this study, hydrogen peroxide solution as a disinfectant and hydrogen peroxide activated with cold plasma of atmospheric pressure of the dielectric barrier as a treatment after harvesting blood oranges and comparing the changes in the qualitative properties of the samples with the traditional method of using fungicide and hot water were monitored on days 0, 15, 30, 45 and 75. The results of the periodical tests showed that the pH value in all the samples except for the control group had a downward trend and decreased at the end of storage. And the pH of the control sample increased. The results of the monitoring of dissolved solids during 75 days showed an upward trend in all four treatments, and no significant difference was observed between the four treatment groups after the end of Mani storage. Acidity decreased in all groups. The highest and lowest acidity were related to PH2O2 treatments and sample without C treatment, respectively. The amount of ascorbic acid in all four treatment groups decreased over time, and the lowest decrease was related to fungicide samples. The highest amount of TSS/TA related to the control sample and the highest and lowest percentage of weight loss were observed in the samples of PH2O2 and H2O2 treatments, respectively. |
