Abstract

Epigallocatechin gallate (EGCG), a bioactive component found in green tea, has generated significant interest as a potential alternative to artificial food additives. Its unique properties make it a promising candidate for developing eco-friendly polymers for food packaging. This review explores the potential of EGCG in enhancing the safety and quality of packaged food items. Known for its strong antioxidant and antimicrobial properties, EGCG’s primary function is attributed to its ability to eliminate free radicals and reduce peroxidase activity. This makes it a viable option for incorporation into active and intelligent polymer packaging systems to extend shelf life and preserve food freshness. However, water solubility and lack of thermal stability pose challenges that require careful optimization of performance in packaging materials. The review provides a comprehensive overview of recent advancements in integrating EGCG into packaging materials, formulation techniques, processing methods, and its use to enhance the effectiveness of food packaging. Further, it discusses the potential future research approaches aimed at maximizing the benefits of EGCG to enhance the sustainability and efficiency of food packaging.
