Green tea entrapped by inorganic capsules was incorporated into melted material and extruded without compromising its quality. The shelf-life of fresh meat from two types of active packaging was significantly extended for 3 0.25 days compared to blank samples. Significant difference was observed after 9th day of study in case of results of CIE L*a*b*, MetMb and organoleptic assay. Migration study of antioxidants from the materials was also performed by UHPLC-MS/TQ using food simulants. Amount of migrated catechins was in the range between 6.3 0.25 ± 0.25 3.3 and 228.4 0.25 ± 0.25 15.2 0.25 µg/kg (ratio 6:1). Regression coefficients (R) between 0.9925 and 0.9989 were obtained. Minimum LOD (0.001 0.25 µg/g) and LOQ (0.004 0.25 µg/g) were obtained for epicatechin gallate and catechin gallate while maximum LOD (0.057 0.25 µg/g) and LOQ (0.191 0.25 µg/g) were obtained for catechin. info:eu-repo/grantAgreement/ES/MEC/FPU-AP2012-2716 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.116 2017 FOOD SCIENCE & TECHNOLOGY 25 / 133 = 0.188 2017 Q1 T1 1.201 2017 Chemistry (miscellaneous) 2017 Q1 Industrial and Manufacturing Engineering 2017 Q1 Food Science 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0003-2685-5739 Nerín, Cristina Universidad de Zaragoza Alfonso, María José Caballero, Miguel Ángel 2009 750 Universidad de Zaragoza Dpto.
