The challenge associated with the structural elucidation of unknowns was undertaken using both ultra-high-performance liquid chromatography coupled to an ion-mobility separation quadrupole-time of flight mass spectrometer and gas chromatography mass spectrometry. A total of fifty compounds were observed to migrate from the corks, and among these additives such as antioxidants (Butyl 4-hydroxybenzoate, Irganox 1010, Irganox 1075, Irgafos 168 and BHT) or lubricants (EBO and octadecanamide, N,N'-1,2-ethanediylbis-) were identified. A high proportion (84%) of the detected compounds was non-intentionally added substances (NIAS), and included several cyclic oligomers with different chain sequences. NIAS, such as 2,6-bis(1,1-dimethylethyl)-4-ethyl and 7,9-ditert-butyl-1-oxaspiro[4.5]deca-6,9-diene-2,8-dione, break-down products, including hexa-, hepta- and nonadecanamide, N,N'-1,2-ethanediylbis-, and oxidation products were also identified. One cork was found to be unsuitable for use as a food contact material. info:eu-repo/grantAgreement/ES/DGA-FEDER/T53-20R info:eu-repo/grantAgreement/ES/MICINN/RTI2018-097805-B-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 8.8 2022 CHEMISTRY, APPLIED 5 / 72 = 0.069 2022 Q1 T1 NUTRITION & DIETETICS 5 / 87 = 0.057 2022 Q1 T1 FOOD SCIENCE & TECHNOLOGY 9 / 142 = 0.063 2022 Q1 T1 1.624 2022 Analytical Chemistry 2022 Q1 Medicine (miscellaneous) 2022 Q1 Food Science 2022 Q1 14.9 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Canellas, Elena Universidad de Zaragoza (orcid)0000-0003-2638-9221 Nerín, Cristina Universidad de Zaragoza (orcid)0000-0003-2685-5739 Dreolin, Nicola Goshawk, Jeff 2009 750 Universidad de Zaragoza Dpto.
