In this study, ‘Rabbab’ pomegranates (Punica granatum L.) were subjected before storage to single-layered wax coating (SLW), double-layered wax coating (DLW), individual-seal film packaging (ISP), tray wrap film packaging (TWP), and combined treatments of SLW + ISP or SLW + TWP. Treated fruits were then stored at ambient temperature (15–20 °C; 45–50% relative humidity – RH) or in cold conditions (5 °C ± 0.5; 85% RH) for 18 weeks.
