Abstract Radio frequency (RF) treatments are often used for disinfestations while maintaining the quality of postharvest agricultural products. The purpose of this research was to determine the efficacy of RF treatments for disinfesting mung beans. A pilot-scale, 27 MHz, 6 kW RF unit was used to study the heating uniformity of 6.0 kg mung beans in three different packaging methods heated from 25 °C to 54 °C, and the quality of RF treated mung beans was evaluated. The results showed that the best treatment was achieved by using an eight-layer polypropylene packaging method, an electrode gap of 12.5 cm for heating 5 min, 54 °C surface forced air heating, and 6 min 54 °C forced air holding due to the low heating uniformity index. Then a single layer of forced room air was used for cooling to avoid quality degradation. There was no significant difference in the moisture content, water activity, protein, starch, germination rate, and color values of mung beans before and after RF treatments. Therefore, RF treatments may hold the potential for the effective disinfestations of mung beans.

开发射频加热处理以控制绿豆中的昆虫

摘要 射频 (RF) 处理通常用于灭虫，同时保持收获后农产品的质量。这项研究的目的是确定 RF 处理对绿豆除虫的功效。使用中试规模的 27 MHz、6 kW RF 装置研究了 6.0 kg 绿豆在从 25 °C 到 54 °C 加热的三种不同包装方法中的加热均匀性，并评估了 RF 处理过的绿豆的质量。结果表明，采用八层聚丙烯封装方式，电极间隙为12.5 cm，加热5 min，54 °C表面强制空气加热，54 °C强制空气保持6 min，达到最佳处理效果。加热均匀性指数低。然后使用单层强制室内空气进行冷却以避免质量下降。RF处理前后绿豆的水分含量、水分活度、蛋白质、淀粉、发芽率、色值等均无显着差异。因此，RF 处理可能具有有效杀灭绿豆的潜力。
