“…The wavelength in RF ranges from 22 to 360 times longer than that of microwave frequencies [ 8 ], which makes it a preferred option for pest control in bulk materials such as grain because of the low dp at low frequencies, as indicated in Refs. [ 3 , 15 , 20 , 58 , 59 , 62 , 63 ]. However, the greatest challenge in employing RF radiation for insect control is the inevitable nonuniform heating, as reported in Ref.…”

“…In Ref. [ 104 ], adult R. dominica individuals were placed inside a nylon mesh bag, which was then positioned in the center of a polyethylene box filled with grain. The lethal temperature for adult R. dominica remains constant across different host materials, attributed to the close permittivity values among them.…”

“…The latest published data for germination rate of seeds affected by RF heating are listed in Table 3, including changes in the germination rate of seeds and RF processing modes. Until now, many researchers have successfully used RF heating for eliminating pests in postharvest seeds including oilseeds (Yu et al ., 2016) and cereals seeds (Cui et al ., 2020; Ramirez‐Rojas et al ., 2020). However, most of the experiments are conducted on the single batch processing mode.…”

Food-borne or plant diseases mainly rely on the spread of seeds with pathogens. It is vital to eliminate food/seed-borne pathogens of seeds and their products before commercial import/export or circulation. Radio frequency (RF) heating is identified as an effective method with lack of chemical residues, rapid or volumetric heating and large penetration depth, and also validated as a potential physical method to eliminate pests or pathogens in agricultural products or foods. Although, many reviews have summarised the applications of RF treatment during the process of foods, little comprehensive review has been focused on seeds and their products pasteurised by the RF energy. Comprehensive summary about principles and main applications of RF energy for pasteurising seeds and their products was reported in this review. This review also introduced some typical RF heating systems, thermal death kinetics of pathogens, influences of RF heating on germination rate of seeds and some ways for improving uniformity of RF heating. Furthermore, this review recommended the future research directions about treatment of seeds and their products using RF energy, especially for seed industry to control the pathogens in seeds without reducing their quality after RF treatments.

Tribolium castaneum (Herbst) infestation is inevitable during the storage of semolina and its derivative products. This study applied the emerging radio frequency (RF) heating technology to disinfest T. castaneum in semolina, using a 40.68 MHz, 10 kW RF unit. In the context of considering the quality of semolina, .8 A RF current load with 8 min exposure time was found to be optimum and effective for attaining 100% disinfestation of T. castaneum in semolina. Changes in moisture content, color and gluten content were determined in RF treated semolina to evaluate the effect of RF heating. Mortality of all life stages of T. castaneum was 100% at 64.40 ± 1.40°C of semolina during RF heating. The susceptibility of T. castaneum to RF heating was egg > pupa > larva > adult. Gluten variance was minor, confirmed by SEM micrographs showing slight differences in structure compared to untreated semolina. This supports RF as an eco‐friendly method for semolina disinfestation, making it a promising innovation.Practical ApplicationsThis study applied RF disinfestation method for T. castaneum in semolina, research findings in the study indicates that RF treatment for disinfestation of T. castaneum obtained a good result with 100% mortality. The RF treated semolina had a less color variance, significant moisture reduction, compared to control and slight difference in gluten network and starch molecule structure of RF treated semolina compared to untreated semolina.
