This review highlights antioxidants' role in enhancing functional performance in biodegradable food packaging, suggesting improvements in sustainability.
This review summarizes the recent advances in the incorporation of antioxidants into biodegradable polymer-based food packaging materials. Natural antioxidants such as polyphenols, carotenoids, and vitamins, as well as selected synthetic compounds, are discussed in the context of their origin, mechanism of action, and application methods including blending, encapsulation, and surface coating. The review also compares antioxidant efficiency across various biopolymer matrices including PLA, chitosan, PHA, PBAT, PVA, TPS, and PBS. Special attention is given to the functional performance, regulatory considerations, and future prospects of active packaging systems aimed at prolonging food shelf life and enhancing sustainability.
