Abstract

In this study, polylactic acid (PLA)/cinnamon bark oil (CBO) films were prepared via solvent casting method and characterised for their physical, optical, mechanical, and antioxidant properties. A 15 % loading of CBO significantly (p < 0.05) improved the water vapour barrier, tensile strength, and elongation at break, while its effects on film thickness and water solubility were insignificant (p ≥ 0.05). At a 30 % CBO concentration, the films exhibited over 99 % UV light blockage at wavelengths of 200, 280, and 400 nm. Antioxidant assays demonstrated strong radical scavenging activities, with maximum DPPH and ABTS scavenging values of 93.30 % and 99.40 %, respectively. Controlled phenolic migration studies were conducted using aqueous (10 % ethanol), lipophilic (50 % ethanol), and acidic (3 % acetic acid solution) food simulants to investigate the behaviour of the PLA/CBO film and their antioxidant activities in various food systems. The migration results followed an exponential time-dependent trend, with the highest migration in 50 % ethanol, indicating the films’ efficacy in preventing oxidative deterioration in fatty foods. These findings demonstrate the potential of PLA/CBO films as active and sustainable packaging materials, offering enhanced barrier, mechanical, and antioxidant properties compared to pure PLA films, making them promising candidates for reducing food waste and extending product shelf life.

期刊介绍： Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
