群体感应是细菌之间的一种细胞密度依赖型信息交流机制，越来越多的研究证明，细菌群体感应与食品腐败变质过程之间存在复杂而紧密的联系，有望成为食品保鲜技术领域中一个极具应用前景的新靶点。本文概述了微生物群体感应、群体感应对食品腐败变质的影响和群体感应抑制剂3个方面的研究进展，重点介绍了食源细菌的群体感应研究进展和群体感应对食品(水产品、肉及肉制品、乳及乳制品和果蔬)腐败变质的影响，旨在为新型食品保鲜技术的开发提供理论指导。%Quorum sensing (QS) is a cell-to-cell communication mechanism used by bacteria to regulate their collective behaviors in a cell density-dependent manner. In recent years, an increasing number of empirical evidences had demonstrated that there was a complex and close relationship between food spoilage and bacterial QS. QS has received much attention as a novel target for food preservation recently which has great applied prospects. This article reviewed some progresses in QS, the effects of QS on food spoilage and QS inhibitor, and the research progress of QS in bacteria isolated from food and the effects of QS on food (such as aquatic products, meat and meat products, milk and milk products, fruits and vegetables) spoilage were emphatically introduced. The aim of present paper is to provide theoretical guidance for the development of new food preservation technology.
