摘要：In this study, drying behavior of Trabzon persimmon (Diospyros kaki L.) which grown in Kahramanmaras has been investigated as experimentally. Experiments have been made in a convective dryer at three different drying air velocity (U=0.5 m/s, 1.0 m/s and 1.5 m/s) and at three different drying air temperatures (40, 50, and 60 °C). The experimental moisture data were fitted to some thin layer models (namely Henderson-Pabis, Lewis and two-term exponential models) available in the literature. The two-term exponential and Henderson - Pabis models were found to describe the drying characteristics of persimmon better. The variations of diffusion D eff and mass transfer coefficients h m with the drying air velocity and drying air temperature have been determined and these coefficients were increased with incre asing ve locity and t emperat ure . Also, e ffe ct of the drying air temperature on change of color, water activity and protein of persimmon was determined.
