Abstract

This experiment was conducted the season of 2003 and 2004 on apple fruits (M. domestica) var. Delicious grown under environmental condition of eastern part of Libya ,at El-Gable El- Akhder region . The objective of this study was to determine the proper storage temperature (0 , 3 and 5° C,) for keeping Delicious fruits cultivar in high quality for long storage period (5 months).

By following up the changes in the chemical and physical characteristics as well as wastage (due to pathogen infection) of the fruits, the results indicated that the firmness of the fruits and their content of acidity and total soluble solids were significantly and gradually reduced by rising storage temperatures, while weight loss and wastage percentage increased by increasing storage temperatures. Generally storing the fruits had lowering their firmness and the acidity values. Furthermore the result pointed out that Delicious fruits had good storability potential even at 3°C because the wastage loss and wastage of those fruits still commercially acceptable. But those storage at 0 ° C were superior either in taste or flavor (due to greater retention of acidity, total soluble solids ,firmness) or in lower percentage of weight loss and wastage. And may stand either for a longer storage duration than the studied one (5 months) or had a long shelf life at the marked . From anther point of view , due to the high sugar (TSS) level in locally grown delicious fruits there are opportunity to test storing those fruits at temperature regime does not recommended in the review.
