Abstract

The analysis of samples of dual-ovenable cookware articles has identified chemicals with the potential to migrate into food. Samples were analysed by dynamic headspace analysis at 200 degrees C using a Tenax TA trap cooled in ice, and/or solvent extraction, followed by gas chromatography/mass spectrometry. Plastics analysed were crystalline poly(ethyleneterephthlalate) (cPET), thermoset polyester, poly(ethersulphone) and poly (4-methyl-pent-1-ene) (TPX). The greatest number and quantity of chemicals with the potential to migrate were found in thermoset polyester.

摘要

对可双温烘烤炊具制品样本的分析已识别出有可能迁移至食物中的化学物质。样本通过在200摄氏度下使用置于冰中的Tenax TA捕集阱进行动态顶空分析和/或溶剂萃取，随后进行气相色谱/质谱分析。所分析的塑料有结晶聚对苯二甲酸乙二酯（cPET）、热固性聚酯、聚醚砜和聚（4-甲基-戊-1-烯）（TPX）。在热固性聚酯中发现了数量最多且含量最大的有可能迁移的化学物质。
