| Summary, etc. |
Food spoilage due to microbial contamination and inadequate packaging<br/>contributes significantly to global food waste, with nearly 14% of food lost before retail<br/>for fruits and vegetables accounting for nearly half of this loss. This study aimed to<br/>develop a bioactive chitosan-based film incorporated with varying concentrations (0%,<br/>0.2%, 0.5% and 1.0%) of Kamias (Averrhoa bilimbi) leaf extract (KLE) for food<br/>packaging. The films were assessed based on their physicochemical, durability,<br/>mechanical, barrier, thermal, and biodegradation properties enhanced film thickness,<br/>density, color, opacity, and water resistance. FTIR analysis confirmed successful<br/>incorporation of KLE, while Light microscopy and SEM revealed increased surface<br/>roughness at higher KLE levels. The film with 0.5% KLE demonstrated the highest<br/>tensile strength (117.96 MPa) while 0.2% KLE yielded the greatest flexibility (62.44%<br/>elongation at break). Thermal analysis indicated increased heat stability with higher KLE<br/>content. Soil burial tests revealed slower degradation with increasing KLE, especially at<br/>deeper burial depths, indicating improved durability. Antimicrobial activity, tested using<br/>the disc diffusion method against Escherichia coli and Staphylococcus aureus, showed<br/>partial inhibitory effects in the control chitosan film. However, the addition of KLE did<br/>not improve antimicrobial performance under the tested conditions. Despite this,<br/>consumer evaluation favored films with 0.2% and 0.5% KLE for usability and<br/>acceptability. |
