Abstract

The proliferation of foodborne pathogens amplifies concerns over food safety and environmental sustainability, posing significant risks to human health and necessitating eco-friendly packaging solutions. Herein, novel antimicrobial, biodegradable films were developed from methylcellulose (MC), psyllium husk (PH) and Ocimum tenuiflorum essential oil (OEO). The MC-PH/OEOx (x = 0, 2.5, 5.0, 7.5%) films were analyzed using spectral, optical, morphological, and mechanical techniques. Fourier transform infrared spectroscopy confirmed molec- ular interactions between OEO and the MC-PH/OEO0 films. Mechanical analysis showed that higher OEO con- centrations increased elongation at the break while reducing tensile strength and Young’s modulus, thereby enhancing film flexibility. Additionally, OEO reduced water vapor permeability and moisture content, signifi- cantly improving barrier properties. The MC-PH/OEO7.5% film significantly inhibited Escherichia coli growth, displayed robust antifungal activity, and exhibited potent antioxidant capabilities due to OEO bioactivity. These enhanced physical and biological improvements render MC-PH with OEO a promising, sustainable, and natural solution for food packaging applications.
