Article Synopsis
- Electrospun fibers, while desirable for their features, are mechanically fragile and require support, leading to the development of bio-based multilayer films using strong sage seed gum-gelatin as outer layers and zein-pomegranate extract in the middle.
- These multilayer films showed improved thickness (0.18 to 0.25 mm), tensile strength (increased from 60.8 to 70.2 MPa), and reduced permeability to water vapor and oxygen by 72.4% and 82.6%, respectively.
- The research demonstrates significant enhancements in antioxidant activity and antimicrobial properties as the electrospun layer thickness increases, indicating potential for sustainable packaging solutions.
In the current study, the sage seed gum/gelatin-TiO (SG/Ge-TiO) nanocomposite films were prepared. Their physical, mechanical, chemical, barrier, surface, structural, and microbial characteristics are determined as a function of different ratios of sage seed gum (SG) to gelatin (1 to 2, 2 to 1 and 1 to 1) and different concentrations of TiO nanoparticles (0, 2, 4 % based on biopolymer (w/v)). The results indicated increases in the tensile strength, elongation at break, thickness, brightness (L*), whiteness index (WI), and contact angle, as gelatin content and concentration of TiO nanoparticles increase.
