Abstract

The aim of this study is to investigate the effect of different drying the fruits tomato under different drying systems (sun, solar and oven), different chemical treatments (Citric acid 2% and without treatment) and different fruit tomato sizes (half fruit, quarter fruit, fruit strips of 7 mm, fruit strips of 5 mm and fruit strips of 3 mm) on the quality of dried tomato fruits. The results indicate that the accumulated weight loss of fruit tomato for fruit treated by citric acid 2% lower than those the fruit without treatment. The accumulated weight loss of fruit tomato ranged from 2.00 to 94.73 % for all treatment. The highest values moisture content of fruits tomato were 870.08, 839.32, 819.15, 790.73 and 734.88 % d.b. for half fruit, quarter fruit, fruit strips of 7 mm, fruit strips of 5 mm and fruit strips of 3 mm, respectively. The drying rate of fruits tomato ranged from 0.00 to 177.65, 0.00 to 71.03 and 0.001 to 163.36 kgwater/kgdry base.hr for sun drying, solar drying and oven drying systems. The highest value of drying rate of fruits tomato was 177.65 kgwater/kgdry base.hr was found for 7 mm fruit strips with citric acid 2% before drying for sun drying system. The sugar, ash and lycopene contents of fruit tomato for fruit treated by citric acid 2% before drying higher than those the fruit without treatment.
