Review uncovers bacterial adaptation and resistance pathways to essential oils in food systems, highlighting emerging risks for natural preservation strategies.
Essential oils (EOs) are complex mixtures of volatile metabolites with strong biological properties. Their multi-target mechanisms confer rapid bactericidal activity, lowering the likelihood of resistance development compared to antibiotics. This review examines bacterial responses to EO-induced damage, including adaptation, tolerance, resistance, cross‑adaptation, and collateral sensitivity, which are often overlooked in existing reviews of EOs’ biological efficacy. Additionally, it links EO-adaptation to food, including application methods, biofilms, and interactions with food components.
