•Edible films produced from mechanically deboned chicken meat proteins (MDCM-P).•Thyme, rosemary and clove essential oils were used for enhancement of MDCM-P films.•The lowest WVP was observed from films containing clove essential oil.•Surface roughness of films was decreased with incorporation of clove essential oil.•Clove essential oil can be used for enhancing bioactive properties of MDCM-P films. Thyme, rosemary or clove essential oils at 1.5 % were added to mechanically deboned chicken meat protein (MDCM-P) films, and physicochemical, antioxidant and antimicrobial properties were investigated. Moisture, thickness, and opacity increased, whereas solubility and water vapor permeability decreased with addition of essential oil. The tensile strength of films decreased with essential oil incorporation, while the elongation at break values increased for rosemary and clove essential oil enrichment. Films containing clove essential oil had the lowest roughness value which caused the lowest water vapor permeability. Antioxidant and antimicrobial properties were significantly improved with essential oils, and films containing clove essential oil exhibited the highest activity. It can be concluded that the physicochemical, antioxidant and antimicrobial properties of MDCM-P films could be improved with essential oils and clove essential oil could be the best option when compared with others.
