Mainly porosity of the material was affected
on transfer of mass rate and phenomena of shrinkage
(Mavroudis et al., 1998a) as well as ratio of
rehydration. The size and shape of the produce was
affected by the surface area to volume ratio of the
material with solution. So solute impregnation was
controlled the surface phenomena, solute uptake was
favored by high specific surface values (Lerici et al.,
1985; Torreggiani, 1993).
