摘　　要：脉冲强光作为一种新型食品非热杀菌技术,以其高效、便捷、环境友好等优势逐渐成为研究热点。脉冲强光的穿透性强、杀菌谱广,应用广泛,同时还可以保留食品质地、风味和口感,具有十分广阔的研究前景。然而,目前脉冲强光杀菌机理缺乏系统性的研究,研究方法杂乱多样,不同效应之间的协同机制还不明确。基于上述问题,本文总结脉冲强光杀菌机理以及近年来该技术在食品领域中的应用。首先利用VOS viewer软件和文献计量学方法分析脉冲强光杀菌的研究现状,为掌握脉冲强光杀菌技术的研究动态和发展方向提供准确的信息和线索;其次从脉冲强光作用过程中产生的生物物理效应、光热效应和光化学效应3个方面出发,梳理脉冲强光对细菌多靶点、多核心、多系统的作用过程,以期揭示更深层次的脉冲强光杀菌作用机理;最后按照食品种类归纳脉冲强光杀菌的应用。未来,可通过进一步深入对脉冲强光杀菌作用机制的研究,强化与其他杀菌技术的联用,拓展食品杀菌领域的应用范围。As a new non-thermal food sterilization technology,pulsed light has gradually become a research focus for its advantages of high efficiency,convenience and environmental friendliness.Pulsed light has a strong penetration ability and a wide sterilization spectrum,which has found wide application.Pulsed light can maintain food texture,flavor and taste,making it highly promising for research.However,there is currently a lack of systematic research on the mechanism of pulsed light sterilization;although a wide range of methods have been applied,the synergistic mechanisms between different effects are still not clear.In this context,this paper reviews the mechanism of pulsed light sterilization and its application in the field of foods.First,using VOS viewer software and bibliometric,the current status of research on pulsed light sterilization is analyzed to provide accurate information and clues for understanding the research trends and development directions in the field of pulsed light sterilization technology.Secondly,from the perspectives of its biophysical,photothermal and photochemical effects the process of multi-target,multi-core and multi-system action of pulsed light on bacteria is elucidated to enhance our understanding of the mechanism of pulsed light sterilization.Finally,the application of pulsed light sterilization to different food categories is summarized.In the future,further understanding of the mechanism of pulsed light sterilization and its combination with other sterilization technologies will expand the application scope of food sterilization.
