In this study, γ-cyclodextrin metal-organic frameworks (γ-CD-MOFs) were prepared as promising nanocarriers for gallic acid (GA) and silver nanoparticles (Ag NPs). These nanocarriers (GA-Ag@CD-MOFs) were further incorporated into a zein matrix to fabricate multifunctional composite films, referred to as MOFs-Zein. Scanning electron microscopy (SEM) and atomic force microscope (AFM) analysis indicated that the fabricated composite film exhibited excellent biocompatibility, with GA-Ag@CD-MOFs uniformly dispersed within the film matrix. Fourier transform infrared spectroscopy (FT-IR) result revealed that the incorporation of GA-Ag@CD-MOFs facilitated the formation of intermolecular hydrogen bonds with the matrix polymer. The addition of GA-Ag@CD-MOFs enhanced the tensile strength of the composite film by 19.70 %, improved the water barrier performance by 57.76 %, and provided almost 100 % UV protection. The exceptional controlled release capability of γ-CD-MOFs for GA empowered the composite films to maintain their robust initial antioxidant capacity even after 100 days of storage. Moreover, the composite films performed high-efficiency antibacterial activity against <em>Escherichia coli</em> O157:H7 and <em>Salmonella enterica</em>. Acute toxicological studies showed no histopathology related toxicity was found in GA-Ag@CD-MOFs treated mice. When applied to fresh pork, the composite films significantly reduced the key quality indicators of raw meat, compared to the control film. Overall, this work presents a promising approach to fabricate the composite films as a sustainable and functional solution for green functional food packaging.</p></div>","PeriodicalId":12377,"journal":{"name":"Food Packaging and Shelf Life","volume":null,"pages":null},"PeriodicalIF":8.5,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142231986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, commercial green tea extract was analyzed, revealing that GTE primarily comprised epigallocatechin gallate (EGCG), which conferred potent antioxidant activity determined by the DPPH assay, along with moderate antibacterial activity. The incorporation of 5 wt% of GTE in the extruded films increased thermal stability and Young’s Modulus, and reduced oxygen and water vapor permeability with respect to control PCL/TPG film. Migration studies showed that the release of GTE depended on the type of food simulant, with higher levels observed in an oil-in-water emulsion simulant compared to a non-acidic aqueous food simulant, while no migration of GTE components was detected in dry foodstuffs simulant. Consequently, the antioxidant capacity derived from migrated GTE components were considerably higher in 50 % ethanol than in 10 % ethanol. Furthermore, PCL/TPG-GTE film exhibited antibacterial activity against Gram negative <em>E. coli</em> and Gram positive <em>S. aureus</em> in vitro when tested following the JIS Z2801 standard. The GTE addition also improved walnuts stability, resulting in a reduction and delay of fat peroxidation.
