Due to the ubiquity of plastic packaging, this study evaluated the release of endocrine-disrupting chemicals (EDCs) into liquid foods at various temperatures. Solid-phase extraction (SPE) and gas chromatography-mass spectrometry (GC/MS) methods were used to identify EDCs, including phthalates (BBP, DEHP, DBP), bisphenol A (BPA), and nonylphenol (NP) from cups and containers made of polypropylene (PP) and general-purpose polystyrene (GPPS). The distilled water in PP and GPPS contained no EDCs at 4-10 °C. DEHP, DBP, BBP, BPA, and NP were found in water contained in PP cups and containers at higher temperatures (40-100 °C), with DEHP released the most at 100 °C (1242.5 ± 53.0 ng/L and 1615.3 ± 68.9 ng/L) for water contained in cups and containers, respectively. No BPA, DBP, or BBP was found in the contents of GPPS cups or containers at any temperature. The average EDCs released from PP cups and containers at every storage temperature was significantly higher (P < 0.001) than GPPS. These findings highlight the importance of temperatures and material composition in plastic packaging for food safety. Consumers should be careful when using plastic cups and containers, especially at higher temperatures, as EDC release can pose health risks.
由于塑料包装无处不在，本研究评估了内分泌干扰化学物质（EDCs）在不同温度下向液体食品中的释放情况。采用固相萃取（SPE）和气相色谱-质谱联用（GC/MS）方法，从聚丙烯（PP）和通用聚苯乙烯（GPPS）制成的杯子和容器中鉴定出EDCs，包括邻苯二甲酸酯（BBP、DEHP、DBP）、双酚A（BPA）和壬基酚（NP）。PP和GPPS中的蒸馏水在4-10°C时不含EDCs。在较高温度（40-100°C）下，PP杯子和容器中的水中发现了DEHP、DBP、BBP、BPA和NP，其中杯子和容器中的水在100°C时DEHP释放量最高（分别为1242.5±53.0 ng/L和1615.3±68.9 ng/L）。在任何温度下，GPPS杯子或容器中的内容物中均未发现BPA、DBP或BBP。PP杯子和容器在每个储存温度下释放的EDCs平均含量显著高于GPPS（P<0.001）。这些发现突出了塑料包装的温度和材料成分对食品安全的重要性。消费者在使用塑料杯和容器时应小心，尤其是在较高温度下，因为EDCs的释放可能会带来健康风险。
