This study evaluated the physicochemical, morphological, and functional properties of pectin-based films incorporated with lemon essential oil (EO) to assess their potential as biodegradable food packaging materials. The results showed that EO incorporation significantly influenced film’s characteristics. control film exhibited a smooth surface, while EO-containing had rougher texture globular structures interconnected channels, likely representing dispersed droplets matrix alterations. mechanical analysis revealed increased elongation at break (20.05 ± 0.784%) for EO-incorporated films, indicating improved flexibility, tensile strength Young’s modulus decreased, suggesting reduced stiffness. Film thickness slightly (0.097 0.008 mm) compared (0.089 0.001 mm), though difference was not statistically significant (p > 0.05). Moisture content decreased in (28.894%) (35.236%), enhancing water resistance. Water solubility (16.046 0.003% vs. 15.315 0.040%), swelling rate (0.189 0.003 0.228 0.040; p < 0.05), greater structural stability aqueous environments due hydrophobic nature EO. Transparency tests opacity (0.350 0.02 0.290 0.012), aligning trends UV-protective also moderate antibacterial activity against Staphylococcus aureus Escherichia coli. Antifungal strong inhibition Botrytis cinerea (100%) Alternaria alternata (50%) films. These demonstrate improves pectin antimicrobial activity, environmental stability, making them promising candidates sustainable applications. novel active materials exhibit physical maintaining quality prolonging shelf life.
