Abstract
Osmotic dehydration of eggplant slices in sucrose and sodium chloride solutions at
different solution concentrations, stirring levels and time of process is studied. Water loss and solids
gain kinetics were experimentally determined and modelled using a diffusional model and
equilibrium values were predicted by means of Azuara model. Modelling was satisfactory and
involved effective coefficients of diffusion useful to quantify the different mass transfer fluxes.
