Abstract

This study was conducted during two successive seasons 2020/2021 and 2021/2022 to study the effect of some packing types on the storability and quality of saidy dates (Phoenix dactylifera L.) fruits during the storage period. The post-harvest treatments were packed with perforated or non-perforated polyethylene layers and aluminum foil. The fruits were stored at cold condition 5±1°C with 85-90% RH. Samples of each treatment were randomly taken every two months for 8 months. The results showed that fruit weight loss %, fruit damage %, total soluble solids % and sugar contents were significantly increased with prolonging the storage period. On other hand, the advanced storage period induced a gradual decrease of fruit weight, flesh% and fruit dimensions. All packing with non-perforated either polyethylene or aluminum foil caused a decrease in fruit weight loss and fruit damage percentage as well as fruit weight, flesh% and fruit dimensions compared to use other packing types .Using non-perforated polyethylene result in the least fruit weight loss and fruit damage percentage compared to use other packing types. Using non-perforated polyethylene packing improved the fruit quality during the storage period compared to use perforated polyethylene or either perforated or non-perforated aluminum foil. It could be concluded that using Packing with non-perforated polyethylene maintained fruit freshness without negative effects of fruit quality parameters and seems to be the proper and an ideal packing types to prolong cold storage of saidy dates without great reduction in fruit quality.
