- Abstract
In this study, the changes of some physical and biochemical quality characteristics of Hosui Asian Pear (Pyrus pyrifolia) variety fruits harvested at different stages of maturation were investigated at 0-1 °C and 90 ± 5% relative humidity for 3 months. Changes in physical and chemical parameters such as weight loss, total soluble solid content, titratable acid content, flesh firmness, ascorbic acid content, total phenolic content, total antioxidant content and incidence of internal browning were determined monthly during storage. According to the results obtained, the difference between weight loss of the fruit from different harvest dates were slight. The amount of total soluble solids content increased during storage, while firmness and titratable acidity decreased. Quality changes in the third harvest time fruits appeared more prominently. At the end of the storage period, the lowest ascorbic acid (16.3 mg 100 g-1), phenolic content (574.2 mg GAE 100 g-1) and antioxidant content (0.955 μmol g-1) were detected in the fruit from third harvest. At the end of the 3 monthstorage period, the third harvest time fruits lost marketable quality significantly due to the internal browning rate of 31-55%. When all quality changes are considered, the best storage performance is obtained from the fruits of the first harvest time.
