Each material, including the adhesive, could contain substances that could migrate to the food. In this work, gas chromatography coupled with mass spectrometry and ultra-high-pressure liquid chromatography coupled with quadrupole time-of-flight mass spectrometry were used to identify the biodegradable adhesive compounds. Five of the 13 compounds identified were nonintentionally added substances; they were neoformed compounds created by the reaction of added compounds in the adhesive. Moreover, the migration of the compounds through four different biodegradable materials—paper, polylactic acid, ecovio®, and polyvinyl alcohol—was studied for the first time. Three of the 13 compounds identified in the adhesive migrated from the adhesive to Tenax®, which was used as a solid food simulant. One of them, 2, 4, 7, 9-tetramethyl-5-decyne-4, 7-diol, was an intentionally added substance, and the other two were 1, 6-dioxacyclododecane-7, 12-dione and 1, 6, 13, 18-tetraoxacyclotetracosane-7, 12, 19, 24-tetraone, which were nonintentionally added substances identified in this work. Higher migration values (ranging from 0.81 to 2.07 mg/kg) were observed for migration through ecovio® than through the multilayer made by combination of ecovio® and polyvinyl alcohol (0.07–0.39 mg/kg) owing to the barrier effect provided by polyvinyl alcohol. The migration values for migration through paper and polylactic acid were below the limits of detection.2015http://zaguan.unizar.es/record/16389010.1007/s00216-015-8848-2http://zaguan.unizar.es/record/163890oai:zaguan.unizar.es:163890info:eu-repo/grantAgreement/ES/DGA/T10Analytical and Bioanalytical Chemistry 407, 22 (2015), 6781-6790All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
