摘要:肉制品营养丰富,但极易腐败变质,亟需寻求绿色、高效的保鲜技术。ε-聚赖氨酸是一种天然抗菌肽,
具有抑菌活性高、稳定性强、生物降解性高、安全性好等优点,在食品保鲜和防腐领域极具开发潜力。目前,
基于 ε-聚赖氨酸与成膜材料联合制备的复合膜已成为防腐保鲜技术的研究热点。首先,综述了 ε-聚赖氨酸的基
本性质、抑菌活性及抑菌机制;其次,探讨了 ε-聚赖氨酸对肉制品品质的系统影响;最后,重点介绍了 ε-聚赖
氨酸与蛋白质、多糖、聚乙烯醇等制备的复合膜特性及其在肉制品保鲜中的应用进展。

Abstract: Meat products are rich in nutrition but prone to corruption. Therefore, it is urgent to explore
green and efficient technology for meat preservation. ε-Poly-L-lysine is a kind of natural antimicrobial
peptide and possesses high antibacterial activity, strong stability, high biodegradability as well as good
safety, which has great potential for food preservation and antisepsis. Currently, the composite films
prepared by ε-poly-L-lysine and film-forming materials have become one of the research interests. Firstly,
the basic properties, antibacterial activity and antibacterial mechanism of ε-poly-L-lysine are reviewed.
Subsequently, the effects of ε-poly-L-lysine on the quality of meat products are discussed. Finally, the
characteristics of composite films prepared by ε-poly-L-lysine and proteins, polysaccharides and polyvinyl
alcohol and their applications in the meat preservation are emphatically introduced.
Key words: ε-poly-L-lysine; antibacterial mechanism; meat products; composite membranes; bacteriostasis
