摘要
随着消费者对食品安全与健康需求的提升,传统食品包装的局限性日益凸显。活性包装通过功能成分添加后表现出优异的抗氧化和抗菌等生物活性,成为关注的焦点。茶多酚添加到食品活性包装膜中,可用作抗氧化剂、抗菌剂、交联剂等,从而改善包装膜的理化性质。本文梳理了茶多酚掺入对活性包装膜物理性能(机械性能、光学特征和阻隔特性)与生物活性(抗氧化和抗菌性能)的影响,总结了茶多酚基活性包装膜在食品保鲜中的具体应用,并对未来茶多酚在活性食品包装膜的发展与挑战进行展望,以期为食品绿色包装的开发提供理论依据。
With the ever-increasing consumer awareness on food safety and environment concerns,the application of natural,eco-friendly,biodegradable,and functional films to replace synthetic plastic for food packaging has become a popular research subject by scientists in recent years.To provide or supplement the protective property of a package in preserving the nutrition,quality,and shelf life of the food content in transit and in storage,the concept of“active packaging”has emerged by incorporating functional agent(s)in a film.Among the additives investigated,tea polyphenols(TPs)are known to have antioxidative and antimicrobial properties.In addition,they could chemically crosslink with the film enhancing its mechanical strength,modulating the optical characteristics,and reinforcing the barrier properties.This article reviewed recent advances in the related studies and discusses the development and challenges in further exploration of the active packaging for food applications.
