Abstract: The ecological transition is leading industry towards the use of materials of natural origin, which are often proposed for food contact materials as a sustainable solution to reduce plastic use. They are perceived as safe by consumers; however, a strict control on potential contaminants able to migrate to food and beverages is necessary to assess safety. Thus, the development of analytical methods for the detection and the identification of potentially occurring harmful substances is strongly encouraged, and the combination of different techniques can be a solution to obtain complementary information. In this work, GC-MS, HPLC-MS, ATR-IR and ESEM have been exploited with the aim of monitoring both volatile and non-volatile compounds, and to control surface composition and morphology. Extraction with solvent and migration experiments with simulants were performed on 11 commercial samples, including plates, caps, and wooden coffee stirrers. Global and specific migration studies were carried out, and possible differences before and after use were explored. Analysis after solvent extraction confirmed the presence of additives, and of Non-Intentionally-Added Substances (NIAS) that were also found in migration studies. Data on morphological characterisation were useful to control the item composition, and to check the stability of the materials after repeated use.
