Drying Kinetics of Malaysian Canarium odontophyllum (Dabai) fruit

摘要

Drying method using a hot air chamber was tested on samples of dabai {Canarium odontophyllum) fruit. The drying experiments were performed at three different relative humidity of 10%, 20% and 30% and a constant air velocity of 1 m/s. Drying kinetics of C. odontophyllum fruit were investigated and obtained. A nonlinear regression procedure was used to fit three different one-term exponential models of thin layer drying models. The models were compared with experimental data of C. odontophyllum fruit drying at air temperature of 55°C. The fit quality of the models was evaluated using the coefficient of determination (R2), Mean Bias Error (MBE) and Root Mean Square Error (RMSE). The highest values of R2 (0.9348), the lowest MBE (0.0018) and RMSE (0.0420) indicated that the Page model is the best mathematical model to describe the drying behavior of C. odontophyllum fruit.
