摘要

牛奶通常装在多层塑料袋或纸盒中。这些食品包装材料中的物质,如添加剂、加工助剂、降解产物和残留物,可能会迁移到牛奶中,从而造成污染,危害人体健康。我们研究了六种常用于牛奶包装材料的多层塑料袋和五种多层纸盒中的物质迁移到模型食品(50% 乙醇)中的情况。优化了直接浸泡-固相微萃取-气相色谱-质谱(DI-SPME-GC-MS)方法,用于识别和定量迁移物。最佳萃取条件为 60 分钟的萃取时间、75 °C 的萃取温度和 1000 rpm 的搅拌速率。通过该方法,发现有 36 种化合物迁移到牛奶中,包括几种添加剂(如邻苯二甲酸二(2-乙基己基)酯、柠檬酸乙酰三丁酯和芥子酰胺)、几种降解产物(如 2,4- 二叔丁基苯酚和 7,9- 二叔丁基-1-氧杂螺(4,5)癸-6,9-二烯-2,8-二酮)、一种引发剂残留物和一些溶剂。随后进行的风险评估发现,将六种多层塑料袋中的某些物质暴露于 50% 的乙醇中可能会对人体健康造成潜在风险。我们的研究表明,DI-SPME-GC-MS 是一种快速高效的迁移检测方法,我们的研究结果为多层包装材料中有毒物质可能迁移到牛奶中的风险评估提供了重要参考。

Risk assessment of migrants released from multilayer packaging materials: Direct immersion-solid-phase microextraction coupled to gas chromatography-mass spectrometry
Milk is commonly contained in plastic multilayer pouches or cartons. Substances in these food packaging materials, such as additives, processing aids, degradation products, and residues may migrate into the milk, thereby causing contamination and human health risks. The migration of substances from six plastic multilayer pouches and five multilayer cartons that are commonly used as milk packaging materials into a model food (50 % ethanol) was studied. A direct immersion -solid phase microextraction-gas chromatography mass spectrometry (DI-SPME-GC-MS) method was optimized for the identification and quantification of the migrants. The optimal conditions were determined to be 60 min extraction time, 75 °C extraction temperature, and 1000 rpm stirring rate. Using this method, 36 compounds were found to have migrated into the milk, including several additives (such as bis(2-ethylhexyl) phthalate, acetyl tributyl citrate and erucamide), several degradation products (such as 2,4-di-tert-butylphenol and 7,9-di-tert-butyl-1-oxaspiro(4,5)deca-6,9-diene-2,8-dione), an initiator residue, and some solvents. A risk assessment was then conducted, and it was found that the exposure of certain substances from six plastic multilayer pouches into 50 % ethanol might pose potential human health risk. Our study showed that DI-SPME-GC-MS is a fast and efficient migration detection method, and our findings provide an important reference for the risk assessment of the potential migration of toxic substances from multilayer packaging materials into milk.

期刊介绍: Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
