Water Diffusion Coefficients Of Selected Legumes Grown In Turkey As Affected By Temperature And Variety, Ferda Seyhan Gürtaş, M. Mehmet Ak, E. Özgül Evranuz

Turkish Journal of Agriculture and Forestry

The kinetics of water absorption by chickpeas (Koçbaşı, Kuşbaşı), lentils (green Pul) and beans (Battal, Dermason, Horoz, Şeker) grown in Turkey were studied by a gravimetric method during soaking at 15, 25 and 40ºC to determine moisture diffusivity of these selected legumes. The water diffusion coefficients of the legumes were in the range 9.71x10^{-11} - 5.98x10^{-10} m^2/s for the chickpeas, 3.53x10^{-10} - 1.33x10^{-9} m^2/s for the lentils and 4.35x10^{-11} - 3.79x10^{-9} m^2/s for the beans. An Arrhenius-type equation described the strong temperature effect on the diffusion coefficient with activation energies of 48.6-49.8 kJ/g-mol for chickpeas, 39.7 kJ/g-mol for lentils, and …
