Production of biodegradable sodium caseinate film containing titanium oxide nanoparticles and grape seed essence and investigation of physicochemical properties

In this study, sodium caseinate film was produced and the effect of titanium oxide nanoparticles grape seed essence as factors that enhance properties investigated. For purpose, nanocomposite films based on were modified with different levels 0 to 1.5% at 500 ppm central composite experimental design (CCD). The effects these variables physical/mechanical properties, water vapor permeability, antioxidant morphology chemical structure evaluated by SEM FTIR techniques. results showed addition has improved mechanical films. regard, prepared from have highest tensile strength. scanning electron microscopy test led indirect penetration water, which reduced permeability 4.89 kg/m. caused films, so containing 250 activity 86.74%. Overall, had positive physical caseinate.
