Hydration kinetics of soybeans

Characteristics of the hydration of six domestic cultivar of soybeans were investigated and Arrhenius kinetic parameters for the reaction were determined using the time for soybeans to reach maximum water absorption. The hydration rate of soybeans varied depending on the cultivar and the hydration temperature. As the hydration temperature increased, the hydration rate increased and the time for maximum water absorption decreased. The activation energies varied from 47.42 to 49.44 kJ/mol and the pre-exponential factors varied from 2.08x10(5) to 4.31x10(5) min(-1), respectively.
