Abstract:
In this study tomato was subjected to different drying temperatures (control, 40°C, 50 °C and 60 °C) with slice thickness (6 mm, 8mm and 10mm respectively) to examine their effect on storage period (30 days, 60 days and 90days) on the chemical and bioactive parameters of dried tomatoes powder by using heat pump dryer. In this research, we tested that lycopene content, color (L*, a and b*), TSS, ascorbic acid and proximate analysis and water activity at ambient condition. At 60 °C results in better retention of lycopene (129.1 ± 0.60 mg/100 g), TSS (6.53±0.04 ^oBrix), proximate analysis (65.7±0.06%) L* (35.16±0.06) a* (27.2±0.99), ascorbic acid (32.96±0.2 mg/100 g) while minimum water activity a_w (0.43 ± 0.00) upto 90 days of storage. This study concluded that samples dried at a higher temperature (60 °C) showed effective retention of the bioactive components after drying and during the storage period.
