Rehydration is a process of moistening dry material, mostly, using abundant amounts of water, which causes adsorption of the water and leaching of solutes (Lewicki, 1998). Rapid rehydration with the least solid loss is required for a better quality of rehydrated products. Rehydration properties have been extensively investigated in plant materials, including fruits and vegetables (Krokida and Marinos-Kouris, 2003, Witrowa-Rajchert and Lewicki, 2006 and Marques et al., 2009), while only a few studies have demonstrated the rehydration characteristics of protein-based food matrices (B
