Abstract:
A NMR method based on the analysis of the transverse magnetization decay curve of water protons, was employed to study the hydration process of Ife Brown cowpeas. In order to investigate the role of pH and Ionic Strength (IS) on the hydration process the beans were soaked in solutions at different IS and at different pH-constant IS. The kinetic constant for the hydration process and the water-holding capacity of the seeds in different conditions were measured.
