چکیده مقاله :
In the present research, nylon 6-silver (NS)/ Chitosan (CS)/Rosemary master-batch nanofibers was provided in order to be used in packaging food. Morphology and structure of the nanofibers was investigated using the Scanning Electron Microscope (SEM) and Fourier-transform infrared spectroscopy (FTIR). The antibacterial activity of synthetic nanofibers was evaluated for E. Coli and S. Aureus bacteria. The antioxidant activity of oxidant glucose of glucose oxidase and Rosemary as well as the function of the provided membranes in packaging and maintaining strawberry was investigated. Morphology and diameter of synthetic nanofibers were determined with SEM images. According to the results of the carried out investigations on the deterrent effect of silver on the activity of glucose oxidase of 70/30 NS-CS sample was selected as the optimum for subsequent studies, and based on the results, the highest enzyme activity (79.5%) with 0.05 grams of glucose oxidase was obtained. The antibacterial test of the membranes showed the perfect antibacterial activity of such membranes against the negative and gram-positive and gram-negative bacteria. In addition, the FTIR spectroscopy approved the presence of glucose oxidase, silver, and Rosemary in synthetic membranes.
