Antimicrobial potential of polylysine in edible films, Food Science and Technology Research, 17(4), 375-380. doi:10.3136/fstr.17.3751344-66061881-3984http://doi.org/10.3136/fstr.17.375https://hdl.handle.net/11147/4919The antimicrobial activity of edible films from whey proteins, alginate, zein and chitosan incorporated with polylysine (PL) and PL- ethylenediaminetetraacetic acid (Na 2EDTA) combination have been tested on different bacteria including Escherichia coli, Listeria innocua, Salmonella Typhimurium and Stapylococcus aureus. The PL-containing films of whey proteins, alginate and chitosan were effective on L. innocua, but had limited effect on E. coli. On the other hand, the PL-containing zein films showed good antimicrobial activity on both E. coli and L. innocua as well as on S. aureus. PL-Na 2EDTA combination also gave zein films effective on S. Typhimurium. The incorporation of PL alone or PL-Na 2EDTA combination did not cause any significant change in mechanical properties of zein films. Zein has a good potential to develop novel antimicrobial packaging materials incorporated with PL.eninfo:eu-repo/semantics/openAccessAlginateAntimicrobial packagingChitosanPolylysineWhey proteinZeinArticle2-s2.0-8095512284010.3136/fstr.17.37510.3136/fstr.17.375
