Abstract
Mass transfer during osmotic dehydration was studied. The effective diffusion
coefficients for water and solute diffusion were determined assuming osmotic
dehydration to be governed by Fickian diffusion. Solution of Fick’s law for
unsteady-state mass transfer was used to estimate the effective diffusion coefficients. The
average effective diffusion coefficients (De) obtained by this method could predict the moisture
(r2¼0.95) and solid (r2¼0.96) content to a sufficient accuracy. A high degree of correlation
was observed between predicted and experimental values of moisture and solid content.
