Plant-based materials are increasing been used as an alternative to conventional plastic materials in food packaging applications. Thus, for example, bamboo-based food contact articles are gaining popularity owing to their environmentally friendly connotations. However, the evaluation of its safety has been barely addressed. Components of these materials can migrate into the food leading to consumer exposure. Their identification is key for risk evaluations. In the present study, the chemical composition of a great variety of bamboo-based food contact articles including plates, chopsticks, etc. was explored. The volatile and semi-volatile fractions were analysed by gas chromatography-mass spectrometry (GC-MS). Volatile components were concentrated in a Purge & Trap system and semi-volatile compounds were analysed after a methanol extraction. A great diversity of compounds was tentatively identified, some considered toxic (e.g., 5-hydroxymethylfurfural). In addition, a sample suspected of containing melamine was analysed by LC-MS and melamine and its derivatives were detected.
在食品包装应用中，植物基材料越来越多地被用作传统塑料材料的替代品。例如，竹制食品接触制品因其环保内涵而越来越受欢迎。然而，对其安全性的评估却几乎没有涉及。这些材料的成分会迁移到食品中，导致消费者接触。对它们的识别是风险评估的关键。在本研究中，对包括盘子、筷子等在内的多种竹制食品接触制品的化学成分进行了探索。通过气相色谱 - 质谱联用仪（GC-MS）分析挥发性和半挥发性成分。挥发性成分在吹扫捕集系统中浓缩，半挥发性化合物在甲醇萃取后进行分析。初步鉴定出了多种化合物，其中一些被认为是有毒的（例如5-羟甲基糠醛）。此外，对一个疑似含有三聚氰胺的样品进行了液相色谱 - 质谱联用（LC-MS）分析，检测到了三聚氰胺及其衍生物。
