Abstract

Mass transfer during osmotic dehydration of pineapple cubes was investigated in a range of temp. (30-50C) and osmotic solution concn. (40-70Brix). Assuming that osmotic dehydration was governed by Fickian diffusion, effective diffusion coeff. for solute and water were assessed. Results showed that these were empirically correlated with temp. and concn. of osmotic solution. Experimental values for the effective diffusion coeff. of solute and water correlated strongly with predicted values (R2 = 0.96 and 0.99, respectively).
