Abstract :In this study, the effects of open-air sun drying and pretreatment on drying characteristic of cherry tomato insert ignore into journalissuearticles values(Lycopersicum esculentum); were investigated. Drying times were determined as 26 and 22 h for natural and pretreated, respectively. The pretreated samples were dried in slightly shorter time than the natural samples. The drying process took place in the falling rate period. Different seven theoretical drying models were applied to experimental data of falling rate periods. All the models were compared according to statistical parameters; i.e. model efficiency insert ignore into journalissuearticles values(R2);, chi-square insert ignore into journalissuearticles values(χ2); and root mean square error insert ignore into journalissuearticles values(RMSE);. It was observed that Verma et al. model among the models used is best mathematical model represented the open-air sun drying behavior of cherry tomatoes. The best chroma insert ignore into journalissuearticles values(C*); value were obtained in pre-treatment dried cherry tomatoes.
