In this study, mucilage was extracted from fenugreek seeds and essential oil from rosemary. The composite film of fenugreek seed mucilage and eggplant peel powder was prepared with copper nanoparticles (0, 2, 4%) and rosemary essential oil (0, 4, 8%). The physicochemical properties of the prepared films were investigated. According to the obtained results, with the increase of copper nanoparticles and rosemary essential oil, the thickness and antioxidant of the film increases. Humidity, water vapor permeability and solubility of the film decrease with the increase of copper nanoparticles and rosemary essential oil. Also, with the increase of copper nanoparticles and rosemary essential oil, the L* color indices increased and the brightness of the layers decreased significantly. Also, with the increase of copper nanoparticles, the color indices a* increased, but b* decreased. Also, with the increase of rosemary essential oil, the a* color indices have decreased, but the b* factor has increased. The results of antimicrobial activity showed that the addition of copper nanoparticles and rosemary essential oil made the film active against Staphylococcus aureus. Conclusion: The addition of copper nanoparticles and rosemary essential oil to edible films based on fenugreek seed mucilage and eggplant skin powder improved the thickness and antioxidant, solubility, moisture and permeability to water vapor, as well as weakening the brightness.
