Changes in Some Quality Parameters of the Perfect Delight Nectarine Cultivar during Cold Storage and Shelf Life

The objective of this study was to determine storage and shelf life periods of Perfect Delight nectarines grown in Mersin (Yenice, Tarsus). The fruit was kept at 0 °C and 85%-90% relative humidity for 8 weeks. After removal from cold storage at weekly intervals, the fruit was kept at 20 °C and 65%-70% relative humidity for 2, 4 or 6 days to determine shelf life in 3 replicates. Changes in weight loss (%), fruit skin color and flesh color (L*, a*, b*), fruit flesh firmness (N), total soluble solids (%), titratable acidity (g malic acid / 100 ml fruit juice), incidence of chilling injury and fungal decay were monitored weekly during cold storage and during the subsequent shelf life at 2-day intervals. The fruit lost 4%-6% of its initial weight after 8 weeks of cold storage and showed no visible symptoms of shriveling. Fruit flesh firmness decreased, but remained at about 20 N at the end of 8 weeks of storage. Perfect Delight nectarines can be kept at 0 °C and 85-90% relative humidity for 4-6 weeks and can have a 2-day shelf life following cold storage.
