This study was conducted to determine the effect of osmotic dehydration on air drying characteristics of pomegranate arils. Osmotic dehydration was performed at different time and temperatures combinations. Mass transfer parameters were studied using response surface methodology. After osmotic dehydration, the arils were air dried till moisture content became 8.0%. Page model of drying was fitted on experimental data. Osmotic pretreatment decreased the exponential coefficient of the model. Osmotic dehydration conditions and air drying constant were combined in a single mathematical model with optimization at lowest time for overall dehydration. This goal was achieved when the arils were pretreated for 93 minutes at 39°C. This research might help to choose drying conditions for pomegranate arils on an industrial scale.
