Effects of different maturity stages on cold storage of ‘Saurani’ olive variety
Abstract
Although olive cultivation is widespread in the Hatay region, studies using local olive varieties with significant potential are quite limited. It can be said that storage time affects olive fruit and oil quality, and that the primary factor in olive oil spoilage is the storage of olives in unsuitable conditions between harvest and processing. Fruits of the ‘Saurani’ olive variety grown in Altınözü-Hatay conditions, harvested at 3 different maturity stages according to maturity index, were stored in cold storage at 6 °C and 85‒90% relative humidity for 28 days, and fruit and oil quality were examined. In the study, fruit weight, fruit width and length, fruit index, maturity index, weight loss, fruit peel color (L* and h°) and flesh firmness, oil content, water content, free fatty acidity, peroxide value, UV specific absorbance values (K232 and K270 values, ΔK value), fatty acid composition and fatty acid components were determined. At the end of cold storage of the ‘Saurani’ olive variety grown in Altınözü conditions, fruit peel color L* and h° values decreased. Fruit flesh firmness decreased with maturity and was within acceptable limits during the green ripening period, making it suitable for table consumption. Weight loss and peroxide values increased. Weight losses exceeded 10% at the end of day 28 for all three ripeness levels. While there is no restriction for table olives, the high linolenic acid content of olives should be considered if they are used for oil extraction. Cold storage of ‘Saurani’ olive variety for 21 days at 6 °C and 85‒90% relative humidity for all three ripeness periods was found to be successful in terms of fruit and oil quality.
