Passive modified atmosphere packaging and chilling storage for keeping overall quality of dates

© 2018 International Society for Horticultural Science. All rights reserved.The effect of storage at 0 and 20°C for 30 days with and without a passive modified atmosphere packaging (MAP) on overall quality of `Deglet Nour¿ dates has been studied. After the storage time, the physico-chemical and sensory quality, microbial development and moth infestation (Ectomyelois ceratoniae) of dates were monitored. The storage temperature greatly affected the overall quality of dates, and for one month storage, 0°C was recommended. A MAP of 6 kPa O2 + 12 kPa CO2 showed a positive effect on keeping overall quality of dates at 20°C. In conclusion, chilling and MAP techniques could be recommended for commercial use at industrial scale.
