Caryedon serratus, Corcyra cephalonica, and Tribolium castaneum are major storage pests of peanuts and sesame seeds. Postharvest losses of approximately 20% of these oilseeds are recorded worldwide, with insect pests as a major cause. Chemical fumigation is widespread and harmful, leading to adverse health and environmental effects. Microwave disinfestation of life stages (eggs, larvae, pupae, and adults) of selected insects was carried out in peanuts (Arachis hypogea) and sesame seeds (Sesamum indicum). All life stages of all insect pests were 100% eradicated within 60–90 s because of thermal shock at significantly low power (360–600 W). Physicochemical and microbial analysis demonstrated acceptable quality of both commodities post-treatment. Shelf life studies revealed that treated products can be stored for 9–12 months, while control samples spoiled in <3 months with off-flavor. Microwave shock treatment is a novel technology for complete disinfestation of oilseeds and safe extension of shelf life.

感染花生 ( Arachis hypogea ) 和芝麻籽 ( Sesamum indicum )的花生甲虫 ( Caryedon serratus )、稻蛾 ( Corcyra cephalonica ) 和红粉甲虫 ( Tribolium castaneum )的生命阶段对微波辐射质量的敏感性和影响

Caryedon serratusCorcyra cephalonicaTribolium castaneum是花生和芝麻的主要贮藏害虫。这些油籽中约有 20% 的收获后损失在世界范围内被记录,其中害虫是主要原因。化学熏蒸广泛且有害,对健康和环境造成不利影响。在花生 ( Arachis hypogea ) 和芝麻 ( Sesamum indicum ) 中对选定昆虫的生命阶段 (卵、幼虫、蛹和成虫) 进行微波消毒)。由于低功率(360-600 W)的热冲击,所有害虫的所有生命阶段都在 60-90 秒内被 100% 根除。物理化学和微生物分析表明,两种商品经过处理后的质量都可以接受。保质期研究表明,处理过的产品可以储存 9-12 个月,而对照样品会在 <3 个月内变质并变质。微波冲击处理是一种彻底杀灭油料种子并安全延长保质期的新技术。
