摘　　要：UV-C照射处理属于非生物胁迫下非电离辐射和非加热的物理处理技术。果实在能接受的合适剂量内经过UV-C照射后,可以表面杀菌,抑制腐烂变质,保持化学物质含量、感官品质和营养品质,诱导提高果实的抗氧化成分含量和抗氧化能力,从而增强果实自身的抗病性,最终改善果实的贮藏品质,延长货架期。与其他处理如1-MCP、涂膜和气调包装等结合使用,形成耦合的栅栏技术,可以起到叠加的保鲜效果。另外,UV-C处理技术对环境友好、成本低、效益好、易于推广、处理手段简单易行,已逐步成为农产品保鲜的主推技术,在电商流通过程中可以用于商品化前处理。本研究综述了近5年UV-C处理在采后保鲜和鲜切水果上的应用效果,并对未来的使用进行展望,以期对UV-C技术的推广应用提供理论支持。UV-C treatment is an emerging and abiotic stress technology,and is a non-ionizing and non-thermal physi-caltechnology.By using proper dose of UV-C treatment,it can be used to inactivate microbes on the surfaces of food,reduce the decay rate,maintain phytonutrients content and organoleptic quality.According to the research,the applica-tion of UV-C treatment is effective in increasing the levels of antioxidants content and the antioxidant capacity of fruits,then it can enhance resistance ability of some fruits,and which makes storage qualities better and extend the shelf life.Combining UV-C treatment with other technologies,such as 1-methylcyclopropene(1-MCP),and coating with all kinds of active compositions,and different packaging so on,it can form a hurdle technique which is a combination by two or more treatment,it can result in synergistic or additive interactions when compared to any single preservation technique in some horticulture.In addition,UV-C treatment is an eco-friendly and a cost effective technology which can be carried out easily without complex equipment on post-harvest and logistics and transportation for their commercialization.This critical review aims to summarize the research conducted on the effects of UV-C treatment on postharvest fruits in the past five years,the review draws the current challenges as well as future perspectives.It is hoped to provide valuable insights for the widespread adoption of UV-C treatment technology.
