respectively, which led to the darker finished products. Furthermore, it seemed that the effect of processing time on the slices lightness was predomnated over the effect of drying temperature (Fig. 5). In the other word, slow drying rate kept the product in the moist state for alonger time when compared to fast drying rate, which in turnsgave an enough time for the formation of the Maillard reaction products. A similar finding has been reported for air drying of banana at drying air temperatures of 50◦C and 80◦C (Bainiand Langrish, 2009).
