studied dielectric properties of shelled and in-shell peanuts at several densities, moisture contents, and temperatures in the range of 300e3000 MHz.Dielectric properties of peanuts over different bulk density and moisture content at 23 C between 2 and 18 GHz using a free-space-transmission technique were also reported by Trabelsi and Nelson (2004). However, there are few data for dielectric properties of peanuts over different temperatures and moisture contents at radio frequencies
