Drying Kinetics and Colour Analysis of Moringa Oleifera Leaves

The drying kinetics of (Moringa Oleifera) leaves was investigated at different oven drying temperatures (40, 50 and 60 degrees C) using an established drying mathematical model. The experimental drying data of moringa leaves on the basis of reduced chi-square (chi(2)) and coefficient of determination (R-2), the mathematical model exposed the best fit to the drying curves. The values of coefficient of determination (R-2) and reduced chi-square (chi(2)) at 50 degrees C temperature was (0.998 to 0.999) and (0.009 to 0.0002) respectively. Oven dry at 40 degrees C reveled optimum colour values. (C) 2014 The Authors. Published by Elsevier B.V.
