Abstract<br/>Nanocellulose is one of many promising materials that have garnered the attention of researchers and industries. In this study, cellulose nanofiber derived from sugarcane (Saccharum officinarum) bagasse (SB-CNF) was employed as a reinforcing agent in the fabrication of nanocomposite-based films. The reinforcing effects of SB-CNF concentrations (varying from 10 to 40 wt. %) on the characteristics and functionalities of nanocomposite films were examined for the development of nanocomposite films. The results demonstrated that the film incorporating 30% SB-CNF into the SB matrix exhibited optimal characteristics and was chosen for further evaluation of its water barrier properties. To enhance the water barrier properties of resulting films, different<br/>concentrations of lysozyme (0, 3.5, 7, 10.5, and 14 wt. %) were incorporated into the film matrix.<br/>The addition of 3.5% LZ showed the best concentration for incorporation into SB/30%SB-CNF, as it exhibited superior hydrophobicity (97.60 + 0.79°) and mechanical properties (67.28 - 0.58 MPa), on account of its homogenous surface and strong intermolecular interactions between the lysozyme and SB/30%SB-CNF. For active packaging development, incorporation of Japanese yuzu (citrus junos) essential oil (YEO) into the SB/SB-CNF/3.5%LZ nanocomposite films decreased the film's hydrophobicity (<68.23 - 0.82°) and mechanical strength (<44.56 = 0.44<br/>MPa) while increasing the elongation at break (>5.79 = 0.07%) and transparency (-89.00 + 0.58%)<br/>of the films. An increase in water solubility (>22.70 = 0.75%), water vapour permeability >1.09<br/>= 0.06 g mm/m' d kPa), and swelling ratio were also observed. These results affected the overall water barrier properties of the films containing YEO. On the contrary, there was a significant improvement in DPPH radical-scavenging activity, as the film reached an antioxidant level of 56.23 + 1.19% with the incorporation of 14% YEO. The application of the active nanocomposite films containing LZ and YEO on fresh chicken breast meat samples during frozen storage conditions revealed that the presence of 14% YEO within these films significantly contributed to safeguarding the chicken from spoilage. The resultant SB/SB-CNF-LZ/YEO films offered considerable promise for utilization in a number of active food packaging applications. |
