kernels over the frequency range from 1 to 1800 MHz and temperature between 20 and 60 C with moisture content 3% w.b. using the openended coaxial probe method. developed quadratic polynomial equations for non-salted pistachio kernel samples to explain the relationship between moisture content, temperature and dielectric properties at four specific frequencies (27, 40, 915, and 2450 MHz). Zhu, Guo, Wu, and Wang (2012b) reported that the dielectric properties of chestnut flour decreased with increasing frequency and increased with increasing moisture content and temperature. Boldor,Sanders, and Simunovic (2004) 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
