Abstract

The study was carried out between 2004 and 2005 years in Malatya Fruit Research Institute. The fumigation of 1600, 1800 or 2000 g SO2 were applied for 6, 8, 10, 12 and 24 hr after harvest on dried ‘Hacihaliloglu’ apricot fruits. The loss of SO2, product moisture (%), product temperature, acidity (%), pH and the colour of the apricot fruits were determined after the drying processes on the wooden trays following the SO2 fumigation and during storage periods. The results showed that the average level of the SO2 in the dried apricots was found as 2000 ppm after fumigation as requirement of European regulations. Dried apricot fruits had 2174 ppm of SO2 in 2004 and 1586 ppm of SO2 in 2005 at the beginning of storage and these amounts were decreased to 1284 and 1091 ppm at the end of 12 months of storage in normal atmospheric conditions. The loss of SO2 amount in dried apricots was found to be directly proportional with the initial quantity of SO2. When the level of SO2 in dried apricots was decreased to 1500 ppm, the quality of the product was also decreased and the colour of dried apricots are darkened. As a result of this study, can be recommended that the dried apricots including 2000 ppm SO2 should be marketed after 6 months of storage.
