dc.description.abstractA bioactive film based on gelatin and corn starch with corn stigma extract (CSE) was developed for application to protect the quality of chilled beef. The physical and functional properties of the films were evaluated. It was found that the incorporation of CSE did not affect the thickness and moisture of the films, but reduced the solubility in water. The opacity of the active films was slightly higher than that of the control film. The incorporation of the CSE extract in the films considerably increased the bioactive and antioxidant properties. The application of CSE reduced lipid oxidation by 60% compared with the control (without additive). It is important to emphasize that the pH values remained low until the 7th day of shelf life. The active film also showed antimicrobial activity against mesophilic and psychrotrophic bacteria. The overall results emphasized the potential use of bioactive compounds from the CSE for the production of films intended for food packaging. Practical applications: This study proved the antioxidant and antimicrobial action of corn stigma extract (CSE) incorporated in films to package refrigerated beef. The CSE demonstrated a strong antioxidant action, reducing lipid oxidation by 60% compared with the control, decreasing the count of mesophilic and psychrotrophic bacteria. The compiled results confirm that the active film containing CSE extract can be used as an alternative packaging.en
