Biomimetic polyphenol coatings for antioxidant active packaging applications

摘要: Abstract Oxidative instability of food, pharmaceutical, and consumer products can be promoted by trace metals, especially iron copper, with subsequent propagation free radicals. Plant-derived phenolic compounds that contain catechols are reported to have radical scavenging, metal chelating surface adhesion properties upon polymerization. The objective this study was synthesize biomimetic polyphenol coatings for development antioxidant active packaging materials. Two synthetic routes were explored apply the polypropylene in situ polymerization a mixture catechol catechin oxidative laccase alkaline saline. Both demonstrated potent scavenging capacity, which suggest potential capacity. Dual functionality as antioxidants anchors makes them promising candidate inhibit metal-promoted degradation.
