Convective air drying of apples as affected by blanching and calcium impregnation
The effect of previous blanching and calcium impregnation at atmospheric pressure (AI) or in vacuum (VI) on the rate of moisture movement during the first falling rate period of air drying of apples at 60 °C was studied. It was found that the effective diffusion coefficient of water (Def) calculated...
