Abstract:Food spoilage and biofilm formation associated with food bacteria are an important issues in the food industry. Current studies have shown that quorum sensing (QS) plays a vital role in food spoilage, biofilm formation and the occurrence of foodborne diseases. Therefore, the use of quorum sensing inhibitors (QSI) to interfere with or block bacterial QS systems can be used as an effective means to reduce food spoilage. At present, studies have shown that the active substances extracted from plants have a strong ability to inhibit quorum sensing, and based on the potential of these active substances, plant extracts have been developed as new food preservatives. Thus, this review firstly introduces the concept and types of quorum sensing systems and quorum sensing inhibitors, and then focuses on the research and application of the inhibitory effect of active ingredients in plant extracts on quorum sensing systems, in order to provide a reference for the discovery and screening of safe and efficient QSI from natural plant compounds.
