Abstract
Rehydration kinetics of Salicornia herbacea prepared by vacuum drying at 70 or 80°C was studied at water temperature of 30, 60, and 90°C, respectively. A 2-term 5-parameter exponential decay model was used to describe the rehydration process. The rehydration times for the S. herbacea to reach maximum water absorption (t M ) at each rehydration condition varied depending on the rehydration temperature and the drying air temperature. The inverse of the time (1/t M ) showed linear temperature dependency as described by the Arrhenius-type relationship. The activation energy values for the S. herbacea dried at 70 and 80°C were 17.66 and 21.06 kJ/mol, respectively.
