In this study, biodegradable starch-based nano films were developed by turmeric extract curcuma longa (CC), octaphenyl-polyhedral oligomeric silsesquioxane (POSS), garlic extract with antibacterial properties (GC) and clay nanoparticles. Ag⁺-Mt-POSS-CC-CS, Mt-CC-CS and Mt-GC-CS nanofilms were synthesized as the final products. The antibacterial and surface-active corn starch-based nanofilms that were synthesized were analyzed by using the methods of X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and scanning electron microscopy (SEM). After this, the antibacterial resistances of the corn starch nanofilms against the bacteria Salmonella and Staphylococcus aureus (S. aureus) and their surface-active properties against the bacteria S. aureus, E. coli, Listeria monocytogenes and Salmonella were examined. The synthesized nano films were subjected to migration analyses, which are an important criterion for food packaging films, and their results were compared. According to the results of the analysis, while the starch nanofilms containing garlic showed antibacterial resistance against salmonella and S. aureus bacteria, the starch nano films containing curcumin and octaphenyl-POSS did not form an inhibition zone. Comparing surface activity properties, curcumin and octaphenyl-POSS-containing nano films showed surface activity, while the garlic-containing nanofilms did not show surface activity. This result show that the mechanical properties of nanofilm containing garlic has given stronger results. Migration analysis results show that the synthesized nanofilm has found to suitable for use in the packaging of all food products such as milk products, fatty foods, liquid, acidic and dry foods according to the results of all migration analyses.

In this original research, biodegradable corn starch (CS) and wheat gluten (wg)-based silver nanofilms were synthesized and analyzed by using goji berry extract taurine (ta), garlic extract (GC), whey powder (wh), and montmorillonite clay nanoparticles. Antibacterial-corn-starch-based nano films were analyzed by using the methods of high-performance liquid chromatography (HPLC), Fourier Transform infrared spectroscopy (FTIR-ATR), X-ray diffraction (XRD), dynamic and mechanical (DMA) analysis, and scanning electron microscopy (SEM). In addition, the antibacterial resistances of the corn starch nano films against the bacteria Salmonella and Staphylococcus aureus (S. aureus) and Listeria monocytogenes were examined and the migration assays were carried out. The migration analysis results of CS₁, CS₂, and CS₃ nanocomposite films were found as 0.305, 0.297, and 0.297 mg/dm², respectively. The inhibition zone of CS₁, CS₂, and CS₃ nanocomposite films were found as 1547, 386, and 1884 mm² against Salmonella bacteria. The results show that silver nanofilms are suitable as packaging films for the production of packaging in milk and dairy products, liquid foods, and acidic foods.

In this study, the chitosan, a polysaccharide, was encapsulated with the bee pollen and the apple cider vinegar. The freeze-drying method was used in the encapsulation process. The freeze cooling temperature was determined as −80 °C. The obtained encapsulated chitosan compounds were analyzed by Fourier Transform Infrared Spectroscopy (FTIR) and their molecular weights were determined by the cryoscopy method. The total amount of the phenol compounds and % the antioxidant activity of the synthesized compounds were measured by UV spectrophotometer and, the loading capacity of the polyphenol compounds in encapsulation was determined. The success of encapsulation was calculated based on the % encapsulation efficiency (%EE) calculation. The antibacterial and the surface activity properties of the obtained CSx and CSy compounds were analyzed against Listeria monocytogenes, Staphylococcus aureus, E.coli and Salmonella bacteria using the well diffusion method and the Zeiss microscope. According to the results of the analysis, the total phenol amounts of CSx and CSy compounds were determined as 47 and 50 mg/100 × 10⁻⁶ mgGAE, and the antioxidant activity values of %92.4 and 93%, respectively. The molecular weights were calculated as 67, 85 and 140 kDa for chitosan (CS), CSx and CSy compounds, respectively. The encapsulation loading capacities of antioxidant compounds were analyzed as 84.8% and 90.8% for CSx and CSy, respectively. According to the antibacterial analysis results, the biggest inhibition zones occurred against Listeria monocytogenes bacteria. In surface activity analysis, while the pollen, the apple cider vinegar, the chitosan, CSx and CSy compounds showed high surface activity against four different bacteria, only CSx compound did not show surface activity against S.aureus bacteria, and the significant clean and bright surfaces were obtained against other bacteria.
