Dielectric study of mustard (B. juncea Linn.) at 9.85GHz frequency with variable temperatures

The values of dielectric constant (_p), dielectric loss (_p), relaxation time (_p), conductivity (_p) and moisture content of pulverized samples of Mustard were measured for different packing densities at 9.85 GHz microwave frequency and at different temperature (20°, 35°, and 50°C). Experimental results on powders of different packing fraction (δ r) were used to obtain transformation to 100% solid bulk using correlation formulae. A fair agreement between calculated values and those obtained experimentally was evident. This showed cohesion in the particles of Mustard powder under investigation.
