Fabrication and Characterization of ZnO Nanoparticles-Based Biocomposite Films Prepared Using Carboxymethyl Cellulose, Taro Mucilage, and Black Cumin Seed Oil for Evaluation of Antioxidant and Antimicrobial Activities

Food packaging is often made from plastic, which usually obtained non-renewable resources. The development of new technologies, like biocomposite films, has been driven in response to environmental concerns as well consumer demands for eco-friendly, high-quality products derived nature. Biocomposite films were prepared by incorporating taro mucilage, carboxymethyl cellulose (CMC), ZnO, glycerol, and black cumin seed (BCS) oil. SEM results showed that the containing mucilage (TM), BCS oil had noticeably smoother surfaces. FTIR analysis indicated existence a -OH group, N-H bond, alkaline C-C, C=N, C-H, C-O-H, C-O-C bond formation, confirming interaction CMC, oil, ZnO nanoparticles, TM. TGA DSC suggest TM into CMC polymer matrix increased thermal stability. addition significantly water uptake capacity, antioxidative property, tensile strength, elongation at break, with decreased whiteness index solubility. film inhibited growth Staphylococcus aureus Escherichia coli foodborne pathogens. can be potentially used environment-friendly antimicrobial additional research.
