Abstract :Impacts of different pre-treatment insert ignore into journalissuearticles values(citric acid, blanching and salt water dipping); and drying circumstances on Rainbow trout insert ignore into journalissuearticles values( Oncorhynchus mykiss ); fillet samples at the cabinet laboratory type dryer was analyzed. Drying tests were carried out at 40, 50 and 60°C, respectively. According to the obtained conclusions the moisture content was considerably affected by the pre-treatment type and drying air temperature. When compared the drying times of Rainbow trout fillet samples, it was observed that blanched>citric acid>salted ³ natural. The drying data for the moisture ratio versus time was fitted to 4 different thin-layer models. The best fit for the simulated drying models was specified by use of the highest determination of coefficient value insert ignore into journalissuearticles values(R 2 );, the lowest reduced chi-square insert ignore into journalissuearticles values( χ 2 ); value and the lowest root mean square error insert ignore into journalissuearticles values(RMSE);. The Midilli et al. model was found out as the most appropriate model in explicating the drying properties of Rainbow trout fillets.
