摘要：
Listeria monocytogenes poses an increasing challenge to cheese production. To minimize the risk of bacterial contamination, a chitosan-coated nisin-silica liposome was engineered for the present study. We investigated the characteristics of nisin-silica liposomes and the anti-listeria effects of a chitosan-coated nisin-silica liposome on Cheddar cheese. The encapsulation efficiency of nisin in a liposome was sharply increased after it was adsorbed on a silica particle surface. Chitosan-coated nisin-silica liposomes displayed sustained antibacterial activity against L. monocytogenes, without affecting the sensory properties of the cheese. Chitosan-coated nisin-silica liposomes could be a promising active antimicrobial for cheese preservation.
