The aim of this study was to investigate the effects of 1.5, 3.0 and 4.5 kJ/m2 UV-C illumination doses on the postharvest quality of fresh fig (cv. Bursa Siyahi). For this purpose, fruit were stored at 0 ºC temperature with 90-95% humidity for 21 days and some fruits were kept at 20 °C for 3 days to simulate a period of shelf-life. UV-C treatments did not affect fruit firmness, total soluble solids, and titratable acidity content during cold storage and shelf-life. On the other hand, UV-C doses increased total phenolic content and antioxidant activity compared to control. In both storage conditions, 3.0 and 4.5 kJ/m2 UV-C doses were found to be more effective to control unmarketable fruit rate. In conclusion, a 4.5 kJ/m2 UV-C illumination dose can be effective in maintaining the postharvest quality of fresh fig fruit harvested at a 2/3 maturity stage.
