Abstract: Essential oils are liquid, natural compounds that are extracted from fruit processing residues. They contain several components such as: limonene, linalool, flavans, alkylamines, among others. These oils are widely used in the pharmaceutical and cosmetics industries, and are becoming widely used in the food industries, since their properties make it possible to replace chemical compounds and improve the quality of food. This research aimed to evaluate the antibacterial potential of wild orange and coriander essential oils on some bacteria. These oils were impregnated into discs suitable for antibiograms measuring 6 mm in diameter; distributed in Petri dishes with appropriate culture media, previously seeded with the following microorganisms: Bacillus cereus, Bacillus subtilis, Escherichia coli, Salmonella Enteritidis, Salmonella Typhimurium and Staphylococcus aureus, subsequently incubated at 35º C/24 – 48 hours. The analyzes were carried out in duplicate and those with halos equal to or greater than 10 mm were considered to have efficient antimicrobial action. The best results were observed for coriander essential oil, which effectively inhibited all tested bacteria (halos of 90 mm). The best efficacy of wild orange essential oil was observed on B. cereus, B. subtilis and S. Typhimurium (halos of 25 mm). The most efficient antimicrobial activity was observed for coriander essential oil on all bacteria.
