摘要

Mucilage is an excellent substitute for biodegradable packaging material and is readily available in agro-wastes. In the present study, antimicrobial and potentially biodegradable composite films are formed using Abelmoschus manihot root mucilage (AM) and guar gum (GG). An antibiotic known as Metronidazole (MTZ) was incorporated in concentrations of 0.5%, 1%, and 1.5% (w/w), and its influence on the film’s physiochemical, mechanical, and antimicrobial properties was assessed. Findings suggest that the MTZ films exhibit effective UV blocking from 280 nm to 400 nm, increasing tensile strength from 1.68 MPa to 3.75 MPa while reducing elongation from 27.30% to 24.06%. The incorporation of MTZ shows the highest antimicrobial activity with a microbial inhibition zone of 15.44 mm against Salmonella spp., indicating its potential as a sustainable packaging material for microbial-sensitive food products.
