However, this type of material can release after its oxidation off-odour compounds that affect the organoleptic properties of packaged food. Odour compounds released from both polyethylene and oxobiodegradable polyethylene before and after oxidation under a free radicals flow were investigated after 1 day, 2 days and 3 days of oxidation. The samples were analysed using headspace solid phase microextraction followed by gas chromatography-mass spectrometry and headspace solid phase microextraction coupled to gas chromatography-olfactometry-mass spectrometry. Sixty-two different odorous compounds were identified. 4-methylthio-2-butanone (fruit), nonanal (fat) and 3, 6-nonadienal (fat) were present in different materials before oxidation. Multiple headspace-solid phase microextraction has been used to quantify all analytes. The most abundant compound was (Z)-3-hexenyl hexanoate with a concentration range between 1.5791±0.1387 µg/g and 4.8181±0.3123 µg/g. Compounds such as 2-dodecenal, 2-octenal, 2-pentanol, 3-nonenal, 3, 6-nonadienal, ethyl 3-methylbutanoate, ethyl octenoate, hexanone, isopropyl hexanoate, octanal were below their LOD evaluated using MS detector; however, they were detected by gas chromatography-olfactometry. The minimum LOD and LOQ were 0.011 µg/g and 0.036 µg/g, respectively. 000163895 536__ $$9info:eu-repo/grantAgreement/ES/MEC/FPU-AP2012-2716$$9info:eu-repo/grantAgreement/ES/MICINN/IPT-2011-1662-060000 000163895 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 000163895 590__ $$a4.244$$b2017 000163895 591__ $$aCHEMISTRY, ANALYTICAL$$b9 / 78 = 0.115$$c2017$$dQ1$$eT1 000163895 592__ $$a1.186$$b2017 000163895 593__ $$aChemistry (miscellaneous)$$c2017$$dQ1 000163895 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000163895 700__ $$0(orcid)0000-0002-8765-4319$$aVera, P.$$uUniversidad de Zaragoza 000163895 700__ $$0(orcid)0000-0002-1569-7256$$aPezo, D.$$uUniversidad de Zaragoza 000163895 700__ $$0(orcid)0000-0003-2685-5739$$aNerín, C.$$uUniversidad de Zaragoza 000163895 7102_ $$12009$$2750$$aUniversidad de Zaragoza$$bDpto.
