Rehydration kinetics of Salicornia herbacea prepared by vacuum drying at 70 or $80^{circ}C$ was studied at water temperature of 30, 60, and $90^{circ}C$, 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 $80^{circ}C$ were 17.66 and 21.06 kJ/mol, respectively.
