Abstract:

Modified-atmosphere (MA) packaging using bag-in-box Xtend® liners extended the postharvest life of nonnetted Charentais-type muskmelons (Cucumis melo L., Cantalupensis Group, cv. Luna) by delaying over-ripening: excessive softening, change of rind color, decreased soluble solids, and the development of postharvest pathogens. The most delayed fruit ripening was achieved by an atmosphere of 13-14 kPa CO2 and 7-10 kPa O2, even though ethylene concentrations were as much as 120 μL·L-1. Charentais fruit stored in this atmosphere at 6 to 7°C maintained marketable quality for 12 days plus additional 3 days at 20°C. In contrast, lifespan under commercial conditions in air did not exceed 3-5 days at 10 to 11°C plus 3 days at 20°C. The recommended MA was achieved by using the liners with low microperforation level (total perforation area 25 × 10-5 percent of the film surface), 8-9 fruit of total weight ≈5 kg per liner. MA packaging of Charentais melons makes possible their transportation from Israel to Europe by sea instead of air.
