Various strategies are used to reduce postharvest cereal grain contaminants such as insect pests and fungal pathogens. Chemical and physical treatments are common management practices but may leave harmful chemical residues on grains or alter their nutrient content (particularly temperature treatments) and have other limitations. This review explores the recent literature regarding cold plasma, with emphasis on its efficacy for decontamination of postharvest cereal grain from biological contaminants. Cold plasma is an ionised gas containing reactive oxygen and nitrogen species, electrons and free radicals that are lethal to microorganisms and has the potential to decontaminate food surfaces and to increase shelf life. Studies conducted on rice, wheat, corn, barley and oats have demonstrated that cold plasma significantly reduced the amount of fungi, bacteria and their spores on grain surfaces. Cold plasma may also detoxify mycotoxins, and control insect pests. Evidence from various global studies demonstrates the potential use of cold plasma to manage postharvest fungi, mycotoxins and insect pests in Australian stored cereal grain.

采取各种策略来减少收获后谷物的污染物，例如害虫和真菌病原体。化学和物理处理是常见的管理方法，但可能会在谷物上留下有害的化学残留物或改变其营养成分（尤其是温度处理），并且还有其他限制。这篇综述探索了有关冷血浆的最新文献，重点是其对生物污染物对收获后谷物进行净化的功效。冷等离子体是一种电离的气体，其中包含对微生物具有致命性的活性氧和氮物种，电子和自由基，并具有对食品表面进行净化和延长货架期的潜力。对大米，小麦，玉米，大麦和燕麦已经证明，冷血浆显着减少了谷物表面上的真菌，细菌及其孢子的数量。冷血浆还可以使霉菌毒素解毒，并控制害虫。各种全球研究的证据表明，在澳大利亚储存的谷物中，冷血浆可能用于处理采后真菌，霉菌毒素和害虫。
