Research Abstract

The study was performed to evaluate the influence of coating and wrapping treatments used singly or in combination on improving postharvest quality of Manfalouty pomegranate cultivar during 2019 and 2020 seasons. Fruits were coated with any of turmeric oil or ginger oil at 10% and wrapped with waxed paper then stored under cold conditions at (7°C) with R.H 85-90% and analyzed at 2-week intervals to study the changes in physical and chemical quality of fruits. The obtained results revealed that by prolong storage period all the studied fruit properties (fruit weight loss %, fruit decay %, total soluble solids % and reducing sugar %) were increased significantly. However, total acidity % was decreased. All tested treatments had a significant effect on reducing changes in the above mentioned quality parameters but the coating with essential oils, when combined with waxed paper surpassed other treatments in controlling weight and decay. Also, the highest content of total acidity and the lowest percentage of total soluble solids and reducing sugar were recorded in fruits treated with essential oils when combined with waxed paper. Therefore, it could be recommended to use turmeric and ginger essential oils coating in combination with the waxed paper wrapping for improving quality and prolong the storage life of pomegranate fruits. Moreover, the previous treatments can provide a safe and healthy product as they are an alternative to harmful chemical applications
