Future demand of rice is projected to increase with the increase of global population. However, the presence of bacteria, insects, and fungi has resulted in various changes in the physical and chemical characteristics of rice grain. To make it worse, the overuse of post-harvest chemicals (fungicide and pesticide) has caused possible risks to human health through either occupational or non-occupational exposure. For the last few years, cold plasma has been developed as an alternative non-thermal emerging technology for rice grains treatment due to its ability to inactivate or decontaminate pathogens without causing thermal damage and free of any harmful residues. Therefore, this review describes the operational mechanism of cold plasma treatment technology on rice grains, existing reactor system designs, and parameters influenced by the treatment technology (reactor design parameters and treatment process parameters). Possible advanced investigation on future reactor design modification as well as standard operating range of influenced parameters were suggested for improved efficiency and effectiveness of cold plasma treatment.
未来，随着全球人口的增长，对大米的需求预计将会增加。然而，细菌、昆虫和真菌的存在导致了稻谷物理和化学特性的各种变化。更糟糕的是，过度使用收获后化学物质（杀菌剂和杀虫剂）可能会通过职业或非职业接触对人类健康造成风险。在过去的几年中，冷等离子体已被开发为一种替代的非热新兴技术，用于稻谷处理，因为它能够在不造成热损伤且没有任何有害残留物的情况下使病原体失活或去污。因此，本综述描述了冷等离子体处理技术对稻谷的作用机制、现有的反应器系统设计以及受处理技术影响的参数（反应器设计参数和处理工艺参数）。建议对未来的反应器设计改进进行可能的先进研究，并建议影响参数的标准操作范围，以提高冷等离子体处理的效率和效果。
