Although most new biomaterials for food industry applications are labelled '100% natural fabrication' and 'chemical-free', certain compounds may migrate from those materials to the food, compromising the organoleptic characteristics and safety of the product. 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 non-intentionally added substances (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 Ultra-high performance liquid chromatography coupled to ion mobility quadrupole time-of-flight mass spectrometry (UPLC-IMS-MS). 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-hexaoxacyclohexacosane-8,13,21,26-tetrone exceeded the specified limits of migration.
尽管大多数用于食品工业应用的新型生物材料都被标记为“100%天然制造”和“无化学物质”，但某些化合物可能会从这些材料迁移到食品中，从而影响产品的感官特性和安全性。在这项工作中，研究了四种不同生物材料（竹、棕榈叶、木材和麦浆）制成的盘子中化合物的迁移程度。使用三种食品模拟物进行了迁移测试，即 10%乙醇（模拟物 A）、3%乙酸（模拟物 B）和 95%乙醇（模拟物 D2）。即使使用高分辨率质谱技术，也难以明确鉴定非故意添加物质（NIAS），然而，使用超高效液相色谱-离子淌度四极杆飞行时间质谱联用（UPLC-IMS-MS）对迁移测试中的 25 种不同非挥发性化合物进行了鉴定和定量。在竹样品中，三种低聚物，即环状二乙二醇己二酸酯、3,6,9,16,19,22-六氧杂双环[22.3.1]-二十八烷-1(28)，24,26-三烯-2,10,15,23-四酮和 1,4,7,14,17,20-六氧杂环二十四烷-8,13,21,26-四酮超过了规定的迁移限量。
