The antimicrobial activity of ε-polylysine, d-limonene and their combination were evaluated against four food-borne pathogens. ε-Polylysine and d-limonene displayed strong synergistic and useful additive effects against the tested microorganisms. d-limonene nanoemulsion with the inclusion of ε-polylysine, was successfully prepared by high pressure homogenization. The formulations showed an enhanced antimicrobial activity as compared with d-limonene nanoemulsion.
