High CO2 maintains postharvest quality of fresh fig

The aim of this study was to determine the effects of high CO2 with the constant O2 level on the postharvest quality of fig cv. Bursa Siyahi. For this purpose, the atmospheric compositions of3% O2 + 10% CO2 (PA-1), 3% O2 + 15% CO2 (PA-2), 3% O2 + 20% CO2 (PA-3), and 21% O2 + 0.03% CO2 (RA) were tested under a palliflex controlled atmosphere (PA) storage system at 0?C for 28 days. At the end of the storage, weight loss increased during the storage period, but this increase slowed down in all tested PAs compared to RA. PA-1 and PA-2 delayed softening while PA-3 accelerated this process. There were no side effects in fruits stored under PAs for taste. The lowest total microorganism and decay rates were found in PA-2 and PA-3. The fig fruits stored under PAs had higher sugar and organic acid contents compared to the figs stored under the RA. Respiration rate decreased in all PAs compared to the RA. Ethylene productions increased with senescence in all atmospheres, but PA-3 inhibited this increase. Consequently, 15% CO2 (PA-2) can be used to maintain postharvest quality of Bursa Siyahi fresh fig for 28 days at 0 ?C.
