摘　　要：光动力杀菌技术(photodynamic anti-microbial technology,PDAT)是一种基于光源、光敏剂和分子氧组合的非热杀菌技术。随着耐药性病原菌和腐败菌的出现,开发应用新型安全高效的杀菌技术迫在眉睫。由于PDAT的多靶点作用模式,其被认为是一种很有潜力的有害微生物控制方法。文章主要对光动力技术中光敏剂与光源的选择、杀菌效果、杀菌作用原理及其在不同种类食品保鲜中的应用研究进行了综述,为PDAT对食源性病原菌和腐败菌的杀灭及其在食品保鲜中的应用和未来发展提供新思路。Photodynamic anti-microbial technology(PDAT)is a non-thermal sterilization technology based on the combination of light source,photosensitizer and molecular oxygen.With the emergence of drug-resistant pathogens and spoilage bacteria,the development and application of an innovative sterilization technology with high safety and efficiency is imminent.Due to the multi-target action mode of PDAT,it is considered to be a potential method for the control of harmful microorganisms.This paper summarizes the selection of photosensitizers and light sources,antibacterial effect,antibacterial principle and its application in different kinds of food preservation,providing new ideas for the killing of foodborne pathogens and spoilage bacteria by PDAT,together with its application and future development in food preservation.
