Abstract

Graphical abstract: Graphical abstract Highlights: Encapsulated LEO was successfully produced by ionic gelation process. Chitosan films with LEO microspheres and cranberry juice were developed. The effect of LEO microspheres and cranberry juice in the films were investigated. LEO microspheres and cranberry juice improved some of the chitosan film qualities. Chitosan films with LEO microspheres and cranberry juice showed antimicrobial activity. Abstract: Research about biodegradable antimicrobial films continues to receive a lot of attention due to the plastic pollution crisis and the need for environment-friendly and safe food products. In this study, we developed chitosan-based antimicrobial films using a combination of encapsulated lemon essential oil (LEO) by ionic gelation and cranberry juice and evaluated the performance of the films. Our results indicated that the incorporation of LEO microspheres and cranberry juice into the chitosan films improved the UV barrier and thermal properties as well as antioxidant activity of the films. The increase in antioxidants was consistent with the chemical components in LEO and cranberry juice as determined by GC–MS; some of which possess antioxidant properties. Furthermore, following antimicrobial activity test, considerable inhibition halo of 11 and 20 mm were observed respectively against fungi Candida albicans and Penicillium roqueforti, particularly in presence of the film containing both LEO microspheres and cranberry juice.
