Sumac (Rhus coriaria) cultivated mainly in the Mediterranean region, Eastern and Western North America, South Africa, and Asia is rich in phenolic compounds, especially tannins, anthocyanins, and flavones. For this reason, the sumac extract has the potential to be incorporated in the films that could be used as active packaging material. For that purpose, this study aimed to develop the best biodegradable and eco-friendly active food package made from faba bean flour and sumac extract. To evaluate the films, the physical (moisture content, solubility, water vapor permeability, mechanic, opacity, and color), antioxidant, and antimicrobial properties and the chemical and thermal characteristic of films were investigated. While sumac incorporation decreased the water vapor permeability (WVP) of films, the opacity, tensile strength, and elongation at break of films increased. The potential radical scavenging activities of the films were tested with two different methods (2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2MODIFIER LETTER PRIME-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS)), and the results proved the films' enhanced antioxidant activity, especially the highest sumac concentrations. The addition of sumac extract also increased the thermal stability of the films. Antimicrobial activity of the films was also tested on Gram (-) Escherichia coli (ATCC 11229), and Gram ( +) Staphylococcus aureus (ATCC 43300) bacterial cultures, and the film with the highest sumac concentration (FB_S_4) had inhibitory activity on S. aureus showing 26-mm clear zone. To illustrate the effect of active packaging on real food systems, the chicken breast was packaged with FB_S_4 film at refrigerator storage (4 degrees C). Although chicken meat packed with faba bean film without sumac extract (FB) spoiled within 3 days, chicken packed in FB_S_4 film exceeded the microbial threshold at the end of day 7. Therefore, sumac extract-incorporated films can be suggested as a potential food package to extend the shelf life of perishable foods.
