is a foodborne pathogen, the causative agent of listeriosis. Infections typically occur through consumption of foods, such as meats, fisheries, milk, vegetables, and fruits. Today, chemical preservatives are used in foods; however, due to their effects on human health, attention is increasingly turning to natural decontamination practices. One option is the application of essential oils (EOs) with antibacterial features, since EOs are considered by many authorities as being safe. In this review, we aimed to summarize the results of recent research focusing on EOs with antilisterial activity. We review different methods via which the antilisterial effect and the antimicrobial mode of action of EOs or their compounds can be investigated. In the second part of the review, results of those studies from the last 10 years are summarized, in which EOs with antilisterial effects were applied in and on different food matrices. This section only included those studies in which EOs or their pure compounds were tested alone, without combining them with any additional physical or chemical procedure or additive. Tests were performed at different temperatures and, in certain cases, by applying different coating materials. Although certain coatings can enhance the antilisterial effect of an EO, the most effective way is to mix the EO into the food matrix. In conclusion, the application of EOs is justified in the food industry as food preservatives and could help to eliminate this zoonotic bacterium from the food chain.
是一种食源性病原体,是李斯特菌病的病原体。感染通常通过食用肉类、鱼类、牛奶、蔬菜和水果等食物发生。如今,食品中使用化学防腐剂;然而,由于它们对人体健康的影响,人们越来越关注天然去污方法。一种选择是应用具有抗菌特性的精油(EOs),因为许多权威机构认为精油是安全的。在本综述中,我们旨在总结近期针对具有抗李斯特菌活性的精油的研究结果。我们回顾了可以研究精油或其化合物的抗李斯特菌作用和抗菌作用方式的不同方法。在综述的第二部分,总结了过去10年的那些研究结果,其中具有抗李斯特菌作用的精油被应用于不同的食品基质及其表面。本节仅包括那些单独测试精油或其纯化合物的研究,没有将它们与任何额外的物理或化学程序或添加剂结合使用。测试在不同温度下进行,在某些情况下,通过应用不同的涂层材料进行。虽然某些涂层可以增强精油的抗李斯特菌作用,但最有效的方法是将精油混入食品基质中。总之,在食品工业中使用精油作为食品防腐剂是合理的,并且有助于从食物链中消除这种人畜共患病菌。
