Effect of drying conditions on Allahidyen (Salihli) sweet cherries (Prunus avium L.) cultivated in Turkey was studied with the following treatments: dipping in 2 per cent Na2S2O5 for 7 minute, or in 0.5 per cent K2CO3 for one minute at 90°C before drying. The pretreatment were compared with untreated samples. The initial moisture contents of all the samples were 5.4528 gram H2O/gram dry matter (g.H2O/g.DM) while final moisture contents were 0.5254, 0.7796 and 0.6102 g.H2O/g. DM for control, Na2S2O5 and K2CO3 treated samples, respectively. The total soluble solids of dried samples were 66.9 for control, 63.3 and 60.3 per cent for Na2S2O5 and K2CO3 treatments. A decline pattern in ascorbic acid concentration was noted. The anthocyanin extracts from salified samples showed increase in optical density as compare to control and the K2CO3 treated ones. The results indicated that there were no significant differences between the chemical and physical properties of the untreated (control) dried sweet cherries and those treated with Na2S2O5 or K2CO3. Such conclusion enhanced the possibility of drying sweet cherries without any chemical treatments, a trend which will have a direct effect on human health by preventing the harmful effect of chemical additives and supporting the pattern of reaching "food safety". |
