【摘要】 微生物灭活作为鲜切菜加工过程中关键的步骤之一,关系着鲜切菜的保质期与食品安全问题。因此,研究和利用各种除菌技术以延长鲜切菜保鲜期、保证食品安全与质量十分重要。光动力抗菌技术(photodynamic antimicrobialtechnology,PDAT)是一种新兴的食品非热除菌技术手段,利用光生的活性氧自由基(reactive oxygenspecies,ROS)攻击微生物细胞的多个靶点,不易产生耐药性,在鲜切菜领域展现出了巨大的应用前景,为当前研究的前沿热点。考虑到鲜切菜本身具有的生理活性成分与光敏剂之间的相互作用,相比离体实验,PDAT在鲜切菜中的应用效果有限,应将其视为额外的除菌工具,而不是其他传统除菌技术的替代品。本文以鲜切菜的食品安全为出发点,综述了PDAT的原理、方法优势及劣势,鲜切菜的代谢生理变化与PDAT在鲜切菜领域上的应用研究进展与未来发展方向,以期为促进净菜产业的食品安全和PDAT的发展提供依据。

【Abstract】 As one of the key steps in the processing of fresh-cut vegetables, microbial inactivation, is related to the shelf life and food safety of fresh-cut vegetables. Therefore, it is crucial to study and utilize various sterilization technologies to extend the lifespan of fresh-cut vegetables and ensure the food safety and quality. Photodynamic antimicrobial technology(PDAT) is an intriguing emerging non-thermal technology for food sterilization that attack multiple targets of microbial cells by the photogenerated reactive oxygen species, which is not easy to develop drug resistance. PDAT exhibits great application prospect in the area of fresh-cut vegetable, which is of cutting-edge hot research topic. Considering the interaction between biologically active components of fresh-cut vegetables and photosensitizers, the application effect of PDAT in fresh-cut vegetables is limited compared to in vitro experiments.PDAT should be regarded as an additional sterilization tool rather than a substitute for other traditional sterilization techniques. Based on the food safety of fresh-cut vegetables, this review summarized the mechanism and methods of PDAT, as well as its application research progress and future development in fresh-cut vegetables, which is excepted to provide a foundation for promoting the food safety of the clean dishes industry and the development of PDAT.
