China is an important rice producing and consuming country in the world, but pests are extremely prone to occur during rice storage. Many studies have proved that radio frequency (RF) treatments have broad and promise applications in disinfesting grain. A 6 kW, 27.12 MHz RF heating system was used to study the feasibility of controlling lesser grain borer in packaged milled rice, the relationship between insect mortality and RF heating uniformity to further optimize the RF treatment protocol, and the quality changes of packaged milled rice after RF treatment and storage. The results showed that the maximum insect mortality increased with increasing temperature from 52 to 54 degrees C and reached 100% at 54 degrees C for holding 12 min with the smallest RF heating uniformity index. After RF treatment and accelerated storage, all the selected quality parameters of milled rice with 7 brands were not significantly changed, suggesting that the RF treatment protocol may provide effective industrial disinfestation applications.
