| Abstract: |
| Post-harvest disinfection of fresh fruit is the first essential step in post-harvest management. The minimum expectation from disinfectants used in the post-harvest sector is to reduce the microbial load and maintain the quality of the product. Atmospheric pressure cold plasma as an emerging technology is effectively used to inactivate microorganisms, pathogens and improve food safety. Blood oranges were divided into four groups and disinfected with hydrogen peroxide and acetic acid solutions activated by DBD plasma by electrospray and hot water/fungicide system, and the control was considered as an untreated sample. Changes in soluble solids, titratable acidity, ripening index and pH of the treated samples were monitored and compared on days 10, 25, 40 of Mani storage. The samples of hydrogen peroxide and acetic acid activated with plasma had a lower pH than the untreated control at the end of storage. Also, the lowest amount of soluble solids after 40 days of storage were related to acetic acid samples. The hydrogen peroxide samples had the closest TSS/TA value compared to the control samples after the end of Mani's storage. |
