Abstract: Essential oils have been widely used for their properties already observed in nature, as for their antibacterial action, antifungal and insecticidal activities. The aim objective is to verify the antimicrobial action of lavender fine (Lavandula angustifolia), chili pepper (Capsicum frutescens) and ylang ylang (Cananga odorata) essential oils, belonging to the gourmet line, which are suitable for use in gastronomy, allowing the increment of several culinary recipes. Commercial essential oils were impregnated on 6 mm diameter filter paper discs, proper for antibiogram, placed in Petri plates with appropriate culture medium, previously seeded with the following microorganisms: Bacillus subtilis, Bacillus cereus, Escherichia coli, Staphylococcus aureus, Salmonella Typhimurium, Salmonella Enteritidis, subsequently incubated at 35°C for 24 to 48 hours. The evaluation was performed in duplicate and it was considered effective antimicrobial action the ones that showed halos equal or greater than 10 mm. The best results were observed for lavender fine essential oil, which efficiently inhibited all tested bacteria mainly B. cereus, Salmonella Enteritidis (75 mm halos) and Escherichia coli (60 mm halo). The best efficacy was observed for lavender fine essential oil on Salmonella Enteritidis and Bacillus cereus.
