Title: Ion Mobility Quadrupole Time-of-Flight Mass Spectrometry Coupled to Ultra-High Performance Liquid Chromatography for the Identification of Non-Volatile Compounds Migrating from ´Natural´ Dishes

In this work, the degree of compound migration from dishes made with four different biomaterials: bamboo, palm leaf, wood and wheat pulp was investigated. Migration tests were carried out using three food simulants, 10% ethanol (simulant A), 3% acetic acid (simulant B), and 95% ethanol (simulant D2). Unequivocal identification of NIAS is challenging even when using high-resolution mass spectrometry techniques however, a total of 25 different non-volatile compounds from the migration tests were identified and quantified using UPLC-IMS-QTOF. In the bamboo samples three oligomers, cyclic diethylene glycol adipate, 3,6,9,16,19,22-hexaoxabicyclo[22.3.1]-octacosa-1(28),24,26-triene-2,10,15,23-tetrone and 1,4,7,14,17,20-hexaoxacyclo hexacosane-8,13,21,26-tetrone exceeded the specified limits of migration.Read More
