| Abstract | ||||
| The study was carried out at Post Harvest Laboratory, Faculty of Agriculture, Sohag, during the 2021/2022 and 2022/2023 seasons, on Balady orange fruits to determine post - harvest treatment for better quality and desirable shelf life under room storage. The present study was conducted to investigate the effects of Hot water Dipping (HWD), Paraffin Oil, Sodium Bicarbonate (NaHCO3), Low-Density Polye Ethelene film (LDPE), Sodium Bicarbonate plus Low-Density Polye Ethelene (LDPE), Hot water Dipping plus Low-Density Polye Ethelene (LDPE), Hot water Dipping plus Paraffin Oil, Sodium Bicarbonate plus Paraffin Oil and distilled water (assigned as control) on postharvest "Balady" Orange stored under room temperature conditions. The experiment results suggested that the treated orange significantly improved the shelf life of Balady orange as compared to that of untreated ones in both seasons. The results showed that wrapping orange fruits with NaHCO3+ LDPE had the longest shelf life (85, 84) days, whereas untreated orange fruits (the control) had the shortest shelf life (45, 42) days in both seasons, respectively. The highest physiological weight loss was in the untreated (the control) treatment, while the lowest was in warped orange fruits (LDPE). The highest physical and chemical fruit quality was shown in wrapping orange fruits with LDPE | ||||
