A STUDY ON DRYING KINETICS OF INDIAN GOOSEBERRY – AONLA (Phyllanthus emblica Linn.)
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 52
Abstract
Aonla slices were dried at 50, 60 and 700C temperature and the drying rate decreased continuously throughout the drying period. The drying process of aonla slices were carried out in falling rate period. Drying time decreased with increase in temperature. The time taken for tray dryer at 700C was very short for complete drying of aonla slices. Mathematical models were fitted to the experimental data and the performance of these models was evaluated by comparing the coefficient of determination (R2) and reduced chi-square (χ2) between the observed and predicted moisture ratio. Page model gave the best results for describing the drying kinetics of aonla. The tray dried powder at 500C drying temperature found the highest ascorbic acid content followed by 600C and 700C.
