Drying behaviour of spinach leaves was characterized for three levels of temperature (50, 60 and 70°C), two levels of pretreatment (blanched and unblanched) and two levels of dispersed density (30 kg.m−3 and 50 kg.m−3) at a constant air velocity of 1.6 m.s−1. The rehydration and optical density values were optimized for blanched leaves at 70°C temperature and 50 kg.m−3 dispersed density. Rehydration and optical density values varied from 212.66 to 256.58 and 0.43 to 0.67, respectively, with increase in temperature.
