Abstract: Radio frequency (RF) has gained popularity in recent years as an effective mode for disinfestation and safe storage of food grains and other perishables. Apart from providing better heating uniformity, it also has an edge on the disinfestation because of its differential heating ability, but still there’s a lack of data depicting towards its effect on the germination characteristics of the disinfested grains. The disinfested grain samples with different RF levels (180, 190, 200 and 210 mm) providing complete mortality were considered for the germination studies and to optimize the process accordingly. RF disinfestation at 180 mm electrode level proved to affect the most as least germination energy, around 13%, was observed depicting to loss in viability for most of the grains. Apparently, the disinfestation at 210mm, which was having the least electric field density subjected to the sample, had its viability maintained, with germination energy of around 90%. The temperature of the sample in the former varied from 54 to 60 °C, where as in the later it was observed to be around 45 to 48 °C. This increase in the temperature of the black gram grains may be considered as the reason for the loss in viability. This opens up a wide array of unreported facts which needs to be studied as a part of effect laid down by dielectric heating on the food materials.
