Abstract

Cape gooseberry is a Climacteric and temperature-sensitive fruit from the Solanaceae family whose quality and quantity of phenolic and antioxidant substances depend on the temperature and storage conditions. In this research, the effects of calyx coating and storage conditions were investigated on storage life of Cape gooseberry fruits. For this purpose, the fruits were kept in with and without calyx conditions at three temperature levels of 10, 15 and 20 ° C for 30 days. Total soluble solids, titratable acidity, flavor index and vitamin C were measured and evaluated during the time of storage. The results showed that, at the end of storage, the titratable acidity, total soluble solids and vitamin C, decreased significantly, however, flavor index increased during storage period, the increase in total flavor during storage can be due to a significant reduction in the titratable acidity. In addition, at the end of the storage period, the fruits covered with calyx under conditions of temperature of 10c had a good physicochemical quality; the highest titratable acidity (0.633%), soluble solids (14.96%), vitamin C, total antioxidants (59.33%) in fruits covered with calyx under storage conditions 10 ° C were observed.
