Abstract

A study was conducted during two consecutive seasons 2020/2021 and 2021/2022 to investigate the effect of some types of packaging on the storage capacity and quality of Saidy dates during the refrigerated storage period. Types of packing were packaged with cartons and plastic bags perforated or not perforated. The fruits were stored in cool conditions at 5 ± 10 °C and 85-90%RH. All transactions were randomly sampled every two months for a period of 10 months. The obtained data showed a significant increase in the percentage of loss of fruit decay %, fruit weight, sugar contents, as well as % of total soluble solids with the extension of the storage period. On the other hand, the advanced storage period led to a significant gradual decrease in the weight of the fruits. All packaging treatments with carton bags led to a significant decrease % of damaged fruits and the weight of fruits, as well as compared to the use of other types of packaging. The use of non-perforated plastic resulted in a loss of fruit weight and a lower % of damaged fruits compared to the use of other types of packaging. Packaging whole or seedless fruits in non-perforated plastic bags improved fruit quality during the refrigerated storage period compared to packing whole or seedless fruits in perforated plastic or cans. It can be concluded that packing the whole fruits in non-perforated plastic bags maintains the freshness of the fruits without any negative effects on the quality of the fruits and it seems that it is the appropriate and ideal type of packaging to prolong the refrigerated storage of Saidy dates without a significant depletion in the quality of the fruits.
