The present study evaluated Citrus aurantifolia essential oil (CaEO) from lime peel grown in Long An province, Vietnam. Gas chromatography–mass spectrometry analysis identified six bioactive compounds, of which D-limonene (69.99%), β-Pinene (10.28%), and α-Pinene (13.08%) were the most abundant. Physicochemical properties, including relative density (0.9295), absolute density (0.9267 g/mL), acid value (0.5481 mg KOH/g), ester value (0.3123 mg KOH/g), and saponification value (0.8604 mg KOH/g), were determined. The antioxidant activity was evaluated using DPPH and ABTS assays, with IC50 values of 13.99 ± 1.84 and 1.52 ± 0.09 mg/mL, respectively, indicating significant free radical scavenging potential. The antibacterial effect against Staphylococcus aureus (S. aureus), Bacillus subtilis (B. subtilis), Escherichia coli (E. coli), and Salmonella enteritidis (S. enteritidis) was confirmed using the disk diffusion method. The inhibition zones were minimal (approximately 8 mm). In addition, CaEO exhibited a long-lasting aroma, making it suitable for industrial applications. These findings highlight the potential application of CaEO in food preservation, pharmaceuticals, and cosmetics, providing a sustainable approach to utilizing lime peel waste.
