Starch/agar-based functional films integrated with enoki mushroom-mediated silver nanoparticles for active packaging applications

Roy, Swarup | Rhim, Jong-Whan
Silver nanoparticles (AgNPs) were manufactured using the green method mediated by enoki mushroom water extract, and starch/agar functional films were fabricated. The developed AgNPs were small (∼10 nm) and spherical and showed strong antibacterial activity towards foodborne pathogenic bacteria, L. monocytogenes, and E. coli. AgNPs were unvaryingly dispersed in the starch/agar matrix, and the inclusion of AgNPs pointedly enhanced the water vapor barrier and hydrophobicity of the starch/agar-based films. However, adding AgNPs did not affect the films' mechanical strength and thermal stability. Also, the AgNPs-added starch/agar film displayed potent antibacterial activity towards E. coli and L. monocytogenes. Starch/agar films with better physical (mechanical strength, water vapor barrier) and functional properties (antibacterial activity) are expected to be applied in active food packaging.
