摘    要:食品在加工和贮藏过程中易受到有害微生物污染,导致食品腐败变质,造成食用安全隐患。而现在常用的物理或化学保鲜方法虽然可以有效延长食品货架期,但应用范围有限、存在安全隐患且容易造成资源浪费。乳酸菌因其天然、安全、高效的抑菌活性被作为生物保护菌应用于食品中。本文主要从乳酸菌产生的抑菌活性物质、微生物群体感应以及竞争作用等角度综述了乳酸菌的抑菌机制;同时介绍了近年来乳酸菌作为生物保护菌在乳制品、肉制品、水产品和果蔬产品中的最新应用进展,为今后食品高效保鲜提供新思路。

关 键 词:生物保护菌;乳酸菌;抑菌机制;群体感应;应用

Abstract:Food is easily contaminated by harmful microorganisms during processing and storage, which leads to food spoilage and safety risks. Physical and chemical methods are commonly used to preserve food. Although these methods can effectively prolong the shelf-life, they have some shortcomings such as narrow scope of application, safety risks and resource waste. Lactic acid bacteria are used in food as biopreservative agents because of their natural availability, safety and efficient antibacterial activity. This paper reviews the bacteriostatic mechanism of lactic acid bacteria from the aspects of antimicrobial metabolites, quorum sensing and competition, as well as the latest progress in the application of lactic acid bacteria in the biopreservation of dairy products, meat products, aquatic products, and fruit and vegetable products. This review may provide new ideas for safe and efficient food preservation in the future.
Keywords:bioprotective bacteria   lactic acid bacteria   antimicrobial mechanism   quorum sensing   application,
