Abstract:
Using response surface methodology, carrot juice with added malt dextrin was spray dried with an air inlet temperature of 150, 160 and 170 °C and feed flow rate viz., 80, 120 and 160 ml/h. The air pressure was 2 bar and outlet temperature of 75 °C. Fresh carrot juice was concentrated by addition of 8% encapsulating agent (maltodextrin), and then dried using a lab spray-dryer. The physical properties studied were: moisture content, solubility, hygroscopicity, bulk density, color and product recovery. The results showed that the quadratic model used reporting the relation of the independent variables was significant for all the dependent variables.
