The effect of packing density and temperature on dielectric parameters, relaxation time and conductivity of chickpea (Cicer arietinum L.) was assessed. The results showed that there was a systematic increase in dielectric constant and loss factor with increasing values of relative packing fraction and decrease in dielectric constant and loss factor with increasing temperature. Experimental results of different relative packing fractions (8) were further used to obtain transformation to 100% solid bulk using correlation equations of Landau-Lifshitz Looyenga and Bottcher. There was a good agreement between experimental values and theoretical values of differal dielectric parameters. The results showed cohesion in the particles of chickpea powder under investigation.
