Utilization of Modified Atmosphere Packaging to Extend the Shelf-Life of Fresh Figs

Saleh Alturki

Abstract:
The common fig (Ficus carica) variety grown in Saudi Arabia is consumed as unpacked with a limited shelf life. This study examined and monitored the quality parameters to determine the shelf life of fresh figs under refrigerated Modified Atmosphere Packaging (MAP) conditions. The treatments evaluated were: MAP1 (80% CO2, 20%N2, 0.0% O2); MAP 2 tray (20% CO2, 80%N2, 0.0% O2); MAP3 tray (20% CO2, 70% N2, 10% O2); control tray treatment (with normal air); and unwrapped cardboard box. The fruit quality attributes such as decay, fruit size, external color, firmness, weight loss, water activity, water content of figs fruits and total soluble solids were measured during storage at 4°C for more than 42 days. Modified atmosphere packaging with 20% CO2 was successful in reducing the rate of ripening process while the control treatment figs showed signs of ripening development such as significant weight loss and change in figs color. However, the decay incidence was reduced and delayed by all the MAP treatments. The weight loss was less than 1% for all the MAP treatments at the end of storage. The fruit firmness decreased with an increase in weight loss in each treatment after 28 days of storage. There was no significant difference in total soluble solids among the MAP treatments. The shelf life of fresh figs packed in unsealed cardboard box was less than 14 days. In conclusion, MAP resulted in better external appearance and therefore commercial application of MAP in the fresh fig industry should be introduced for fruit preservation.
