This study aimed to select the best conditions for producing a nanoemulsion loaded with an essential oil blend (NEOB) to achieve maximum antimicrobial and antioxidant activities. The NEOB consisted of lemongrass (Cymbopogon citratus; LEO; 60%) and thyme (Thymus vulgaris; TEO; 40%). The effect of ultrasound time exposition at 300 W (5, 18, and 30 min) and essential oil concentration (5, 11, and 20 mg/mL) on these responses was evaluated after obtaining NEOB and after an oxidation assay with UVC-LED exposure. Nanoemulsions were analyzed for their physicochemical and biological properties. Overall, droplet size, zeta potential, minimum inhibitory concentrations (MIC) against Escherichia coli, DPPH free radical scavenging activity, and ferric-reducing antioxidant power were affected by essential oil concentration and/or ultrasound time exposition in a non-linear fashion. The NEOB (average size, 68.88 ± 2.84 nm) with 20.5 mg/mL of essential oil and sonicated for 35.7 min achieved the highest anti-E. coli (MIC, 0.44 mg/mL) and antioxidant activity (FRAP, 1.17 μmol TROLOX equivalent/g), remaining stable even after high UVC-LED doses (6.41 J/cm2 exposure, p < 0.05). This study reveals the promising potential of NEOB obtained from ultrasound for sustainable industrial applications. |
