Herein, two novel eugenol vinyl-based resins were used for coating flexible aluminium foils with potential packaging applications. Coatings were prepared with single eugenol or loaded eugenol in Santa Barbara Amorphous15 (SBA-15) mesoporous silica nanoparticles, and their antioxidant activity was investigated by DPPH, ABTS, ORAC, TBARS assays and by the hydroxyl free radicals’ generator method with HPLC analysis. Antioxidant activity was also evaluated exposing the coatings to various food simulants. Both coatings revealed adequate antioxidant capacity when exposed to fatty food simulants and to vapour phase hydroxyl free radicals (scavenging > 50%). The incorporation of eugenol in SBA-15 reduced its release to 65%, promoting eugenol beneficial antioxidant effects over time. The release of eugenol from the coatings into food simulants is not required for the activity of free radical scavenging. info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 8.5 2023 FOOD SCIENCE & TECHNOLOGY 8 / 173 = 0.046 2023 Q1 T1 1.468 2023 Biomaterials 2023 Q1 Food Science 2023 Q1 Safety, Risk, Reliability and Quality 2023 Q1 Polymers and Plastics 2023 Q1 Microbiology (medical) 2023 Q1 14.0 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Nerín, Cristina Universidad de Zaragoza (orcid)0000-0003-2685-5739 Lavorgna, Margherita Wrona, Magdalena Universidad de Zaragoza (orcid)0000-0003-2052-3012 Russo, Chiara Stanzione, Mariamelia Nugnes, Roberta Isidori, Marina 2009 750 Universidad de Zaragoza Dpto.
