“…On the other hand, Gram-positive bacteria possess thick peptidoglycan layers embedded with lipoteichoic acid, which allows hydrophobic molecules to penetrate and reach the internal environment (Kong et al 2010). Similar inhibitory effects have also been reported for thymol-loaded polymer materials (Davoodi et al 2017, Nordin et al 2021, Zabidi et al 2023.…”

The use of nanomaterials such as cellulose nanofiber (CNF) and antimicrobial compounds such as thymol (Thy), in starch films may improve the functional properties of films as active packaging films. This study quantifies the retention of thymol in corn starch (CS) and CS films containing cellulose nanofibers (CS/CNF) and investigates the migration of thymol from the films into a food simulant. A kinetic study was performed to evaluate the release of thymol from films into fatty acid food simulant (95% v/v ethanol) at 40 °C. The antibacterial activity of films was investigated via liquid culture assay. It was found that the addition of thymol significantly affects the surface morphology and cross-section of the films. CS/Thy and CS/CNF/Thy films retained thymol at 2.88 ± 0.50 and 11.21 ± 0.75 mg per g of CS/Thy and CS/CNF/Thy films, respectively. The release of thymol was affected by the presence of an intercalating network of CNF, which exhibited Fickian diffusion behavior. The release of thymol reached equilibrium within 48 h for CS/Thy, and 72 h for CS/CNF/Thy films. The CS/CNF/Thy film had a greater inhibitory effect than the CS/Thy film against Listeria monocytogenes and Salmonella Typhimurium. These findings demonstrate the potential applications of these films in improving the shelf life of perishable food products.

“…The viscosity (viscosity) of the solution affects the thickness of the edible film (Sjamsiah & Lismawati, 2017). Films derived from starch have a high thickness due to the content of carbohydrates and starch derived from native starch as the main ingredients (Nordin, et al, 2021). Starch at a critical temperature makes the granules immobilize water, swell, and some of the starch will dissolve.…”

Preparation of Edible Film with the Addition of Red Ginger Extract (Zingiber Officinale Var. Rubrum) and Its Application to Tomato (Lycopersicum esculentum) has been carried out. The purpose of this study was to analyze the optimum concentration of adding red ginger extract to edible films on the physical and mechanical properties and to analyze the optimum concentration of adding red ginger extract to edible films on the shelf life of tomatoes. The working principle of making edible films is by varying the red ginger extract 0; 0.25; 0.50; 0.75 and 1% were analyzed by testing the thickness, tensile strength, elongation, young's modulus, and WVTR as well as analyzing the addition of red ginger variations 0; 0.25; 0.50; 0.75 and 1% for testing the shelf life of tomatoes in the form of texture tests and FTIR tests. The addition of red ginger variations had a significant effect (p<0.05) on the thickness, tensile strength, elongation, and modulus of young edible film at the optimum concentration of 0.50% with a thickness value of 0.100 mm, tensile strength 4.696 Mpa, elongation 0.194%, modulus young 26.68 Mpa, and WVTR 15.85 g/m2.hour.
