Preparation and characterization of gelatin/β-glucan nanocomposite film incorporated with ZnO nanoparticles as an active food packaging system

In this study, nanocomposite film as biodegradable active packaging was fabricated by incorporation of gelatin and β-glucan (0, 10, and 20% w/w) in the presence of ZnO nanoparticles (0, 2.5, and 5% w/w); further, it was characterized by XRD, DSC, SEM, and FT-IR analyses. The obtained results exhibit...

Description
Summary:In this study, nanocomposite film as biodegradable active packaging was fabricated by incorporation of gelatin and β-glucan (0, 10, and 20% w/w) in the presence of ZnO nanoparticles (0, 2.5, and 5% w/w); further, it was characterized by XRD, DSC, SEM, and FT-IR analyses. The obtained results exhibited that the incorporation of ZnONPs and β-glucan had no adverse effect on the morphological and thermal properties and the crystallinity of gelatin-based films, indicating appropriate interaction and good compatibility between gelatin matrix, ZnONPs, and β-glucan. Moreover, the increasing concentrations of β-glucan and ZnONPs increased strain to break and the ultimate tensile strength of film samples. The film samples containing a high concentration of ZnONPs showed higher water barrier properties (moisture absorption and water vapor permeability) and surface hydrophobicity. Additionally, the incorporation of ZnONPs in the film samples provided high antibacterial activity against foodborne pathogenic bacteria. In conclusion, the ZnONPs and β-glucan incorporated gelatin-based nanocomposite film could be applied as an active food-packaging system due to its unique features. Graphic Abstract
