SUMMARY:

Films and coatings based on biopolymers show great potential for application in the food industry, especially as active packaging, contributing to increased product shelf life and reduced waste. This study aimed to develop sodium alginate-based polymer films incorporating extracts of Cumaru (Amburana cearensis), recognized for their antimicrobial and antioxidant activities, respectively. Plant samples were collected in the hinterland of Paraíba, and the films were prepared with different concentrations: 60%, 80% and 100% Cumaru. The obtained materials were characterized in terms of homogeneity, thickness, mechanical properties (deformation and tensile strength), color, and antimicrobial activity. The films showed good dispersion and incorporation of the extracts, as well as satisfactory malleability and uniformity. The best antimicrobial activity was observed in the samples containing 100% of the plant extract. The results indicate that the extracts have potential for application as active packaging, representing viable alternatives for preserving chicken meat.
