| Description |
Effects of temp. and concn. of osmotic solution on the osmotic dehydration of bananas were studied; the effective diffusion coeff. of water was also modelled using a cylindrical configuration to approximate the shape of a banana. Effective diffusion coeff. were calculated using Fick's law for unsteady state mass transfer at temp. of 25-35C and osmotic solution concn. of 40-70B. An Arrhenius-type equation was used to empirically correlate effective diffusion coeff. with temp. and concn. of the osmotic solution. Using this model, predicted and experimental values for effective diffusion coeff. were compared, and gave a good level of agreement (R2 = 0.97).
