The aim of this investigation was to identify by GC–O–MS the odorous compounds in five different types of adhesive (hotmelt, vinyl acetate ethylene, starch, polyvinyl acetate and acrylic) used in food packaging. In order to obtain a substantial number of compounds, they were extracted by two complementary extraction methods: HS-SPE and HS-SPME. Fifteen minutes extraction time using PDMS fiber for hotmelt adhesive and DVD/CAR/PDMS fiber for the other adhesives were the best conditions for defining a representative solvent-free adhesive extract using a rapid and simple D-GC–O technique. Thirty-three compounds were identified by GC–O–MS. These include butyric acid, acetic acid, methyl butyrate, 1-butanol and nonanal, which were present in most of the adhesives under study producing cheesy, rancid, sour, medicinal and green aromas, respectively. The concentrations were determined, the most abundant compound being acetic acid with concentrations from 22.9 to 8930 μg g−1 of adhesive. 000163903 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-sa$$uhttps://creativecommons.org/licenses/by-nc-sa/4.0/deed.es 000163903 590__ $$a4.387$$b2012 000163903 591__ $$aCHEMISTRY, ANALYTICAL$$b7 / 74 = 0.095$$c2012$$dQ1$$eT1 000163903 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000163903 700__ $$aUliaque,B. 000163903 700__ $$0(orcid)0000-0003-2638-9221$$aCanellas,E. 000163903 700__ $$0(orcid)0000-0003-1658-1770$$aEscudero,A.$$uUniversidad de Zaragoza 000163903 700__ $$0(orcid)0000-0003-2685-5739$$aNerín,C.$$uUniversidad de Zaragoza 000163903 7102_ $$12009$$2750$$aUniversidad de Zaragoza$$bDpto.
