Summary: The antibacterial activity against food-borne pathogens was investigated using essential oils of the peels of Hallabong (Citrus reticulata ‚Shiranui‘), Redhyang (Citrus hybrid ‘Kanpei’), Cheonhyehyang (Citrus hybrid ‘Setoka’) and orange (Citrus sinensis). In the agar well diffusion assay, citrus peel essential oils showed antibacterial activity against Bacillus subtilis and Vibrio vulnificus. In particular, Cheonhyehyang peel essential oil (10 mg per well) had the highest antibacterial activity against V. vulnificus (a zone of 6.62 mm in diameter). Additionally, octanal showed strong antimicrobial activity against V. vulnificus. The essential oils of the peels of Redhyang, Cheonhyehyang and orange had minimum inhibitory concentrations (MIC) of
