摘　　要：芽孢是某些细菌营养体在环境胁迫条件下形成的休眠体,广泛存在于自然界中。芽孢结构致密,对热、紫外线辐射等环境胁迫具有较强的抗性,很难被食品工业中常规的杀菌方法所杀灭,是影响食品安全的重要因素。近年来,非热加工技术在杀灭芽孢中的应用受到广泛关注。冷等离子体是一种新型非热杀菌技术,具有杀菌效率高、能耗低、无二次污染等优点,在食品工业中有广阔的应用前景。本文综述了冷等离子体杀灭食品中细菌芽孢的研究进展,总结了冷等离子体杀灭芽孢的作用机制,分析了影响冷等离子体作用效果的因素,并展望了今后的研究方向,以期为冷等离子体在食品安全控制领域的实际应用提供理论基础。Spores are the main dormant forms of some bacteria under harsh environment conditions,which are widely distributed in nature.Bacterial spores have a rigid structure,which helps resist to environmental stresses such as heat and ultraviolet radiation.At present,it is difficult to inactivate bacterial spores by the conventional sterilization methods used in the food industry.Therefore,bacterial spores are one of the most important factors influencing the food safety.In recent years,the application of non-thermal processing technologies in killing spores has received great deal of attention.Cold plasma is a novel non-thermal physical sterilization technology,which has a broad application prospect in the food industry due to its various advantages such as high bactericidal efficiency,low energy consumption,and secondary pollution-free.In this paper,the application of cold plasma in the inactivation of bacterial spores in foods is reviewed,and the underlying mechanisms are also summarized in detail.Moreover,the effects of diverse factors on cold plasma-induced spores inactivation are analyzed,and the future research direction is also prospected.This article provides important theoretical basis for the practical application of cold plasma in food safety and quality control.
