Abstract
This paper introduces a novel active carrageenan film designed for meat preservation, featuring the release of antioxidants eugenol (Eu) and α-tocopherol (Tp). The film is composed of semi-refined carrageenan, plasticized with 0.9 % glycerol, and reinforced with 10 % cellulose nanofibers derived from waste biomass. Lipid oxidation was measured through TBARS and percent metmyoglobin to evaluate the film’s effectiveness in extending the shelf-life and maintaining the quality of meat. The film containing 0.4 % Tp demonstrates superior mechanical properties and thermal stability, achieving a tensile strength of 66.79 MPa and an elongation at break of 46.54 %. Notably, it exhibits a significant antioxidant release rate over 25 days, with TBARS and percent metmyoglobin values of 0.652 and 35.98 %, respectively. These results suggest that this biodegradable packaging solution not only prolongs meat shelf-life but also aligns with sustainable practices in food preservation. The release profiles of Eu and Tp follow a first-order kinetic model, indicating a controlled and sustained release mechanism. Overall, these findings highlight the potential of active films in enhancing food packaging solutions while promoting ecofriendliness.
