CONCLUSION<br />
The osmo-<strong>dehydration</strong> <strong>of</strong> a fruit pulp can be described with a thermodynamic model that takes into account<br />
the heterogeneity <strong>of</strong> the system. The experimental data are those relevant to the isothermal desorption trends<br />
across the swept RH range for the original (peeled) and partially osmo-dehydrated fruit pulp, and the<br />
hypertonic sugar syrup used. These trend allow evaluation <strong>of</strong> the mass <strong>of</strong> intra- and extra-cellular phases <strong>of</strong><br />
the system at any given RH. The mass change <strong>of</strong> the intra- cellular aqueous phase allows a rough evaluation<br />
<strong>of</strong> the shrinkage that the fruit cells undergo and the correlation between shrinkage and RH, which may be<br />
applied to any kind <strong>of</strong> <strong>dehydration</strong> treatment, provided it does not affect the cell walls.<br />
