| Summary: | The aim of this work was to develop bionanocomposite films based biopolymer GG and TiO2-NRs for active food packaging. The TiO2-NRs were incorporated as antimicrobials agent into GG via solvent casting method. The films appearance was have 94 % of transparency. SEM micrographs indicate that the TiO2-NRs were successfully incorporated and attached to the surface of developed GG films. FTIR results revealed the interaction between TiO2-NRs and hydroxyl group of GG polymer. XRD results showed the crystalline peaks of TiO2-NRs and amorphous peaks of GG+TiO2-NRs films. The thermal stability of GG films were increasing by incorporation of TiO2-NRs materials. The GG+TiO2-NRs films showed good antibacterial activity against Gram-positive (Staphylococcus aureus (S. aureus) and Streptococcus (strep.)) and Gram-negative (Escherichia coli (E. coli) and Pseudomonas aeruginosa (P. aeruginosa)) and potentially used as antibacterial packaging films. |
