Atmospheric cold plasma (ACP) is an emerging technology in the food industry with a huge antimicrobial potential to improve safety and extend the shelf life of food products. Dielectric barrier discharge (DBD) is a popular approach for generating ACP. Thanks to the numerous advantages of DBD ACP, it is proving to be successful in a number of applications, including microbial decontamination of foods. The antimicrobial efficacy of DBD ACP is influenced by multiple factors. This review presents an overview of ACP sources, with an emphasis on DBD, and an analysis of their antimicrobial efficacy in foods in open atmosphere and in-package modes. Specifically, the influence of process, product, and microbiological factors influencing the antimicrobial efficacy of DBD ACP are critically reviewed. DBD ACP is a promising technology that can improve food safety with minimal impact on food quality under optimal conditions. Once the issues pertinent to scale-up of plasma sources are appropriately addressed, the DBD ACP technology will find wider adaptation in food industry.

大气冷等离子体（ACP）是食品工业中的一项新兴技术，具有巨大的抗菌潜力，可提高安全性并延长食品的保质期。介电势垒放电（DBD）是一种生成ACP的流行方法。得益于DBD ACP的众多优势，它被证明在许多应用中都取得了成功，包括食品的微生物净化。DBD ACP的抗菌功效受多种因素影响。这篇综述对ACP来源进行了概述，重点是DBD，并分析了其在露天和包装方式下在食品中的抗菌功效。具体而言，严格审查了影响DBD ACP抗菌功效的工艺，产品和微生物因素的影响。DBD ACP是一种有前途的技术，可以在最佳条件下提高食品安全性，同时对食品质量的影响最小。一旦适当解决了与等离子源放大相关的问题，DBD ACP技术将在食品工业中找到更广泛的适应性。
