dc.description.abstractIn this study, the drying kinetics, e ff ective moisture di ff usivity (D e ff ) , speci fi c energy consumption ( SEC ) , colour, and shrinkage (S b ) of pomegranate arils were compared when dried by convective ( CV ) drying and microwave ( MW ) drying. The experiments were per - formed at air temperature of 50, 60, and 70°C and air velocity of 1 m/s for CV drying and 270, 450, and 630 W for MW drying. The results showed that increasing air temperature and MW power increased the D e ff. The cal - culations demonstrated that the maximum D e ff for pome - granate arils was obtained for MW drying ( 630 W ) . Maximum SEC for pomegranate arils in the CV dryer was 145.12 kWh/kg, whereas in the MW dryer was 35.42 kWh/kg. In MW dryer, the lowest values of colour change and shrinkage were 6.77 and 50.5%, respec - tively. Comprehensive comparison of the di ff erent drying methods ( MW and CV ) revealed that MW drying had best drying performance for pomegranate arils, considering the drying time, e ff ective moisture di ff usion, SEC, colour, and shrinkagept_PT
