Abstract

Rehydration of dried apples was carried out with continuous measurement of a cube height. It was observed that the height decreases during the early stages of rehydration and, after the minimum is reached, the cube begins to swell. It is suggested that an amorphous matrix is formed in the final stages of drying of apples. Rehydrating water plasticizes the glassy matrix and a structure collapse is observed.

    This deformation of the porous network leads to a modification of the pore size accompanied by a decrease of the porous volume, the surface area and the throat diameter. This series of sintered networks models to some extend the complex imbibition kinetics that characterizes swelling materials found in food [6–8] or textile technologies [9]. The size increase of the colloid, gel or fiber following the uptake of the imbibing fluid may result in variations of the porous network similar to what is produced by the sintering.

    By modifying the extent of the partial dehydration and syrup composition not only can the end product be diversified but chemical, physical and functional properties can be improved. Both osmotic dehydration and air drying could produce great changes in the structure of vegetal tissue, as widely reviewed by Lewicki (Lewicki, 1998; Lewicki et al., 1997; Lewicki and Jakubczyk, 2004). In particular, texture of material moves from elastic–visco-plastic to rigid, becoming fragile and brittle.
