Synthesis of alginate-based antibacterial and antioxidant food packaging films

This study contributes to the preliminary development of active food packaging materials by using bio-based polymers under ultrasonic waves. For this alginate (Algi) polymer was reinforced with functionalized multiwalled carbon nanotubes (COOH-MWCNTs) dispersed in surfactants form A-type films. Similarly, a B-type films, Algi blended polyvinyl alcohol (PVA) presence COOH-MWCNTs. The synthesized films were physiochemically characterized FTIR, SEM, TEM, and mechanical testing. antibacterial antioxidant properties prepared assessed agar well diffusion method ABTS/Ferrozine methods, respectively. Synthesized showed prominent peaks Algi, PVA, COOH-MWCNTs FTIR analysis nanofillers SEM/TEM study. Youngs Modulus AD90 is 249.17 N/mm2, Bs90 216.80 N/mm2 129.55 N/mm2. Staphylococcus aureus positive Klebsiella pneumonia, Escherichia coli are negative strains bacteria that successfully inhibited grow also acted as strong antioxidants no significant difference (P > 0.05) from ascorbic acid compared tested ABTS Ferrozine methods.
