Summary:The effect of temperature and time in a fluidized bed dryer, the concentration of biopolymer treatment and blanching time on quality attributes of dehydrated carrots was evaluated by response surface methodology. Optimization maximized rehydration ratio and minimized bulk density and carotene loss. Based on surface responses and contour plots, optimum conditions were: drying temperature of 150 degrees C, exposure time of 12.5 minutes, biopolymer concentration of 1.40%, and blanching time of 12 minutes. Experimentally determined values for rehydration ratio, bulk density, and carotene loss in product processed under the optimum conditions were very close to the predicted values of 9.5, 0.05, and 15.7%, respectively
