Abstract:
Nanotechnology offers an innovative application as an eco-friendly food packaging film fabricated along with a degradable active mixture (AM). The AM is an assortment of alloyed metal oxide nanoparticles (Ag-ZnO), citron powder (AA), and Curcuma peel powder (CPP). Alloyed nanoparticles (NPs) were observed to exhibit a hexagonal structure from the experimental X-ray diffraction. Compositional and morphological study of the NPs (22.69 nm) and AM (32 nm) was done using energy-dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and ζ- potential was observed to be -14.7 mV, indicating the stability of NPs. The prepared film was observed to be more effective with antibacterial analysis against Escherichia coli, exhibiting 72% of inhibition and antioxidant activity with IC50: 51.56% using the 2,2 diphenyl-1-picrylhydrazyl (DPPH) assay. Film 1, Film 2, Film 3, and Film 4 were fabricated with the AM and observed to be perfectly encapsulated by PVA using XRD. FESEM images of the film exhibit the aggregation of NPs with biocomposites in perfect distribution. The mechanical properties such as Young\'s modulus, elongation at break, tensile strength, and ultimate tensile strength (UTS- 5.37 MPa) were experimented for the films. The degradation rate was observed to be 6.12% for film 1 using the soil burial method. The study emphasizes that NPs along with biocomposite upgrade the sustainability of the packaging film with improved mechanical and physicochemical properties. The synthesized film with biomaterials could be used as a \"green\" food package to store fruits, vegetables, and sweets in the food industry.
