The Algerian date cultivar Deglet Noor (DN) is widely consumed and known for its distinctive taste and light translucent colour, meeting high local and international demand. However, DN fruit is seasonal, highly perishable after harvest and exposed to severe quality loss during storage and shipping, which impacts economic value and marketability. The aim of this study was to test the effectiveness of two types of polypropylene film packaging (micro-perforated and non-perforated film) in maintaining the fresh properties of DN fruit collected in three different locations in Algeria. The main quality attributes were measured at harvest time and monthly during four months of cold storage at 4 °C, followed by four days of simulated shelf-life at 25 °C.

The results obtained showed a substantial difference in the quality preservation of packed date fruit regardless of film porosity compared to conventional unpacked samples. The application of film packaging prior to storage effectively reduced water loss and preserved Algerian DN physical, chemical, and sensory characteristics. These preliminary results represent the first step towards the development and implementation of an effective packaging solution in Algerian storage facilities.
