In this study, Mazafati date samples were dried using a cabinet drier at five temperatures (50, 60, 70, 80 and 90 ˚C) and air flow rate of 1 m/s. Changes of total soluble solids, browning, pH, acidity and color parameters (L*, a* and b*) of date samples during drying were determined and compared. The results showed that total soluble solids, browning index and acidity increased and pH of date samples decreased. Moreover, L* and b* color parameters decreased and a* value increased. Overall, it was concluded that the moisture of Mazafati dates can be reduced by industrial drying. Furthermore, air temperatures of greater than 70˚C have negative effects on color of the date samples. Therefore, drying temperature of 70˚C was found to be the optimum condition for drying process of Mazafati date.
