| خلاصه مقاله | The aim of this work was to produce a novel degradable film with gelatin / chitosan and resveratrol, and the electrospinning process was applied for the encapsulation of resveratrol in nanofibers from gelatin and chitosan solution. The optimized ratio of gelatin: chitosan: resveratrol was found to be 2: 1: 0.05 (w/v/v) after the evaluation of electrospinning solutions and nanofiber physical properties. The results showed that resveratrol could be efficiently encapsulated in micro-nanofibers (88.72 g/100 g). The active layer containing it showed a uniform fiber morphology observed by scanning electron microscope and obtained uniform diameter at 200±4 nm. The tensile strength of nanofibers reached 1.83 ± 0.04 MPa. The diameter of nanofibers was enlarged and the hydrophobicity was enhanced, the antibacterial activity and antioxidant activity were improved as the addition of resveratrol compared with pure gelatin nanofibers. In particular, nanofibers containing 5 μL/mL resveratrol showed the highest antioxidant activity (33.99 mg DPPH/g dry weight), radical scavenging activity (44.80%), and significant microbial growth inhibition with CFU of about 3.2 log units (E. coli) and 2.7 log units (S. aureus) lower than the control. At last, the nanofiber was applied to preserve beef and exhibited antibacterial activity against Listeria monocytogenes during 10-days storage at 4 °C and 7-days storage at 12 °C, without impact on the sensory and surface color properties. In conclusion, our results suggested that active layer could be an effective method to encapsulate resveratrol, and the chitosan/gelatin nanofibers was a novel biodegradable packaging material with great antioxidant and antibacterial activity. |
