Drying Kinetics of Malaysian Canarium Odontophyllum (Dabai) Fruit
Authors: , , ,
Abstract: 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 non-linear 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 55oC. 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 value of R2 (0.9348), the lowest of 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.
