肉类食品生物膜的形成机制及预防措施

Formation Mechanism and Prevention Approaches of Biofilm in Meat Products

在肉及肉制品加工及贮藏过程中,如处理不当就会引起细菌污染,并形成细菌生物膜而造成肉制品腐败、致病。生物膜是具有三维结构的微生物群落,是微生物抵抗外界不良环境的一种特殊生长方式,它可以改善恶劣环境及抑菌剂对微生物的影响。腐败菌和致病菌均可形成生物膜,其对肉制品加工业的危害极大。本文主要概述近5年来国内外关于肉类食品细菌生物膜形成的机制、影响及其预防和控制措施,旨在为肉类食品加工中各种细菌生物膜形成及控制提供理论和应用参考。

During processing and storage of meat and meat products,improper handling will cause bacterial contamination with further the formation of bacterial biofilm and therefore the corruption and pathogenicity of meat products.Biofilm,a microbial community with three-dimensional structure,is a special growth mode for microorganisms to resist the adverse external environment.It can improve the adverse environment and the influence of bacteriostatic agents on microorganisms.Pathogenic bacteria and spoilage bacteria can both produce biofilms,which lead to great harm to the meat processing industry.In this paper,the mechanism,influence and prevention and control measures of bacterial biofilm formation in meat food in recent five years were discussed,aiming to provide theoretical foundation and practical application for the formation and prevention of various bacterial biofilms.
