Contamination of food with chems. migrating from food contact materials (FCMs) is an important area of food safety. This study was aimed to investigate migration of chems. from plastic FCMs used for microwave and conventional oven heating. Migration tests were conducted for samples of microwave trays, microwave oven bags, and oven bags. GC- and LC-Orbitrap mass spectrometry (MS) was used for non-targeted screening and identification of chems. with mass error <5 ppm. A non-targeted identification approach was validated with isotopically labeled chems. to establish acceptable criteria for identification of migrated compounds A total of 74 migrated compounds were tentatively identified: 24 chems. by GC-Orbitrap MS with electron ionization (EI), plus 35 and 19 by LC-Orbitrap MS electrospray ionization (ESI) with pos. and neg. polarities, resp. Four migrated chems. were identified by more than one instrumental anal. Both intentionally added substances (IAS), i.e. additives used in the production of polymeric materials and plastics, and non-intentionally added substances (NIAS), i.e. derivatives and degradation/oxidation products of IAS, were identified among the migrated chems. The levels of 25 migrated chems. were significantly different (p < 0.05) between microwave treatments and conventional oven treatments, where 20 migrants had higher levels for microwave compared with 5 for conventional oven treatments. For several identified chems., no previous reports on their migration from FCMs were found.
