| Abstract | Carrot is widely consumed as it contains bioactive compounds such as carotene. However these are very sensitive to heat. Therefore, degradation behaviors during thermal process should be considered. This study aimed to study kinetics of moisture content, shrinkage and ?-carotene degradation of carrot cubes subjected to hot-air drying. Several empirical models were fitted to experimental data obtained under different hot-air temperatures ranging from 60?C to 80?C. Based on the highest coefficient of determination (R2 ), lowest root mean square error (RMSE) and chi square (? 2 ), the suitable equations were selected and employed to describe the change behavior of moisture, shrinkage and ?-carotene. The results indicated that the Page and Modified Page models, the so-called Ratti model and the 2nd -order reaction kinetics equation suitably described the kinetics behaviors of moisture, shrinkage and degradation of ?-carotene, respectively. Consequently, all suitable kinetics model obtained in this work can be further used as a basis for design and optimization purposes. |
