Description

Fresh figs are highly perishable fruit that needs more care as compared to other fruit during handling and storage. Postharvest life of mature fresh fig fruit is limited to 1-2 weeks. If the proper conditions are not provided, losses can exceed 50% during postharvest chain. Controlled atmosphere storage can be a potential tool in decreasing postharvest losses, improving storage and shelf-life quality of fresh fig due to the high CO2 tolerance. This study aimed to investigate the effects of different atmospheric compositions; 3% O2 + 10% CO2 (PMA-1), 3% O2 + 15% CO2 (PMA-2); 3% O2 + 20% CO2 (PMA-3) and 21% O2 + %0.03 CO2 (PMA- 4) on postharvest quality and losses of fresh fig fruit under palliflex modified atmosphere (PMA) storage system. Fruit were stored at 0 ± 0.5°C temperature and 90 ± 5% relative humidity for 28 days. Additionally, figs were kept at 20 °C temperature and 60-65% relative humidity for 3 days to simulate the shelf life performance. Fruit samples were taken from different storage conditions at 7 days intervals for determination of physical and chemical parameters such as weight loss, fruit firmness, total soluble solids content, glucose, fructose, citric acid and decay development. The tested parameters showed that PMA storage containing 3% O2 + 15% CO2 was the most successful treatment for ‘Bursa Siyahi’ fig cultivar and they can be successfully stored for 28 days under this condition.
