Responses of High Carbon Dioxide Concentration on Postharvest Quality of Fresh Fig Fruit during Storage

The aim of this study was to determine the effects high CO2 with constant O2 level on postharvest quality fig cv. Bursa Siyahi. For purpose, atmospheric compositions 3% + 10% (PA-1), 15% (PA-2), 20% (PA-3), and 21% 0.03% (RA) were tested under a palliflex controlled atmosphere (PA) storage system at 0°C for 28 days. At end storage, weight loss increased during period, but increase slowed down in all PAs compared RA. PA-1 PA-2 delayed softening while PA-3 accelerated process. There no side fruits stored taste. lowest total microorganism decay rates found PA-3. had higher sugar organic acid contents figs Respiration rate decreased Ethylene productions senescence atmospheres, inhibited increase. Consequently, (PA-2) can be used maintain Siyahi fresh days 0 °C.
