Abstract
- Water absorption kinetics in pea seeds (Pisum sativum L.), varieties San Isidro and Sureña, were determined. Rehydration was conducted at three temperatures (6, 18 and 30 °C), using a seed/water ratio 1: 4 (w/v), and measurements at 0, 3, 6, 9, 12 and 24 hours were taken. The effect of temperature was evaluated by the water adsorption capacity, whereas the water adsorption kinetics was studied in two models (Exponential and Peleg). The water adsorption capacity increased with increasing water temperature. The models adequately describe the kinetics of adsorption of water. Both diffusivity and kinetic parameters show dependence on temperature and when are evaluated by the Arrhenius activation energy of 17.24 kJ/mol for San Isidro and 9.25 kJ/mol for Sureña were obtained.
