Its antioxidant performance was tested using DPPH (IC50 = 270 +/- 21 mu g/g) and ORAC (1.52 mu mol Trolox/g). In vivo study was done using fresh minced meat stored at 4 degrees C and analysed after 0, 6, 13, 19, 23 days. After 23 days metmyoglobin (MetMb(BK) = 31.3 +/- 2.9% and MetMb(AOX) = 25.9 +/- 0.8%), CIE L*a*b* (a*(BK) = 15.0 +/- 0.4 and a*(AOX) = 16.6 +/- 0.3) and TBARS (MDA(BK) = 0.0060 +/- 0.0003 mu g/g and MDA(AOX) = 0.0044 +/- 0.0002 mu g/g) showed an improvement of meat shelf life. The results showed that this active film protected meat during 23 days. Migration study to food simulants was done by UPLC (R)-QqQ-MS and UPLC (R)-ESI-Q-TOF-MSE. A decrease of oligomers migration (for caprolactam n = 3: BK = 0.050 +/- 0.004 mg/Kg; AOX = 0.019 +/- 0.001 mg/Kg) was found. Industrial relevance: Nowadays, food industry is focused on improving shelf life of products by controlling its lipid oxidation using natural antioxidants. The obtained results la us design a new active packaging based on natural antioxidants for extending the shelf life of fresh minced meat at industrial scale. info:eu-repo/grantAgreement/ES/DGA-FEDER/T53-17R info:eu-repo/semantics/closedAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 6.306 2019 CHEMISTRY, APPLIED 5 / 70 = 0.071 2019 Q1 T1 NUTRITION & DIETETICS 10 / 89 = 0.112 2019 Q1 T1 FOOD SCIENCE & TECHNOLOGY 6 / 138 = 0.043 2019 Q1 T1 1.775 2019 Analytical Chemistry 2019 Q1 Medicine (miscellaneous) 2019 Q1 Food Science 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Torrieri, Elena Wrona, Magdalena Universidad de Zaragoza (orcid)0000-0003-2052-3012 Nerin, Cristina Universidad de Zaragoza (orcid)0000-0003-2685-5739 2009 750 Universidad de Zaragoza Dpto.
