Physical and Biochemical Changes in Fruits of Some Table Apricot Cultivars during Storage

Increases in production and export values of table apricot, brings out the necessity of determination of the cultivars post-harvest resistance. This study carried out to determine quality change in table cultivars such as Ninfa, Precoce de Tyrinthe, Igdir and §ekerpare during cold storage period. Fruits were kept at 0°C and 90-95% relative humidity for 35 days. Fruits removed from storage room at a week interval were studied for some quality parameters, physiological and pathological disorders. Weight loss of fruits increased with increasing storage period in all investigated cultivars. Modified atmosphere packaging had a positive impact on limiting of this loss. Fruit flesh firmness decreased depending on the storage period, and these values ranged from 17.9% to 10.0%. As the storage period was proceeded total soluble solid of Precoce de Tyrinthe and §ekerpare increased, in contrast, a decrease in Igdir and Ninfa cultivars was found. Titratable acidity ratio of investigated cultivars showed a steady decrease. During storage, the ground color values (a* and b*) increased or decreased according to cultivars. In this study it was determined that the lowest weight loss (0.97%), and the highest fruit firmness (54.32 N) were measured in Igdir apricot cultivar at the end of 35-day storage. Furthermore, in general, this process was found to be similar to quality changes of Ninfa and Precoce de Tyrinthe apricot cultivars.
