長期保存飲料用ペットボトルから溶出する成分の高分解能質量分析による評価
Food packaging materials can contain a wide range of known and unknown substances. These substances are not completely understood and migratable to foodstuffs depending on their characteristics. To ensure the food safety, it is important to elucidate the migration to foodstuff. In this study, the migration from polyethylene terephthalate (PET) bottles to beverage stimulants was examined using liquid chromatography high-resolution mass spectrometry (LC/HRMS). Substances included in PET bottles were structurally identified by non-target analysis. Long-term migration for the identified substances was evaluated by target analysis. Unlike other plastic materials and articles, PET bottles obtained in Japan included less additives. In the examination by non-target analysis using LC/HRMS, PET congeners were the main migrants from PET bottles. Two-year long storage tests with beverage stimulants showed a gradual release of these substances to the contents. The surface processing employed affected the characteristics of migration.
