Impacts of smart and active packaging on the quality and storage period of ‘Barhi’ dates

Abstract

The climacteric nature of ‘Barhi’ dates makes their shelf life very short after harvest. This research aimed to explore the impact of using different packaging materials along with reducing the negative effects of ethylene gas on the quality of ‘Barhi’ date fruit by determining the changes in physical and chemical characteristics of stored fruit. For this purpose, ‘Barhi’ date fruits were picked during the Khalal stage and stored using three different packaging materials [carton boxes (control), low-density polyethylene (LDPE), and equilibrium modified atmosphere packaging (EMAP)] with or without ethylene absorbent sachet (EAS) at 0 °C for 40 days. The results indicated that the EMAP bags with EAS under 0 °C gave the highest quality properties of all studied parameters compared to the control treatment. The control treatment recorded the lowest date fruit quality, which lasted only for 20 days of cold storage before converting to the Rutab stage. Using LDPE with EAS instead of the more expensive EMAP bags could be a cheaper way to keep the quality of ‘Barhi’ date fruit and make it last longer during cold storage.phoenix dactylifera
