The drying characteristics of the tomato slices were investigated at 65, 70, 75 and 80 °C. The tomato samples were dried up to 2-3 % wet basis (w.b). The experimental data of the tomato samples were fitted to the six models; Page’s, Henderson & Pabis, Logaritmic, Wang & Sing, Midilli and Polynommial model. SSE, R2 and RMSE % values were used to determine the suitability of these models for describing the drying curves of tomato slices. Polynommial model gave better results compared to others. Effective moisture diffusivity values (Deff) were found between 5.86.10-9 and 2.505.10-8 m2/s for tomato slices and increasing drying temperature causes an increase in Deff values. The activation energy was found as 24.92 kJ/ mole.
