Epoxidized soybean oil (ESBO) has been used in polyvinyl chloride (PVC)/polyvinylidene chloride (PVDC) food packaging cling film as a plasticizer and stabilizer. The aim of this study was to investigate the migration of ESBO from PVC/PVDC cling film, based on gas chromatography mass spectrometry (GC-MS). The specific migration of ESBO was evaluated using various food simulants (water, 4% acetic acid, 50% ethanol and n-heptane) for PVC and PVDC wrap products. ESBO did not migrate into water and 4% acetic acid for all the tested samples. However, it was released into 50% ethanol and n-heptane in several PVC/PVDC wraps, with maximum migration levels of 38.4 ± 0.7 and 37.4 ± 0.8 μg/mL, respectively. These results demonstrate that ESBO is capable of being released from PVC/PVDC wrap into amphiphilic/oily food and its migration should be regularly monitored.
环氧大豆油（ESBO）已被用作聚氯乙烯（PVC）/聚偏二氯乙烯（PVDC）食品包装保鲜膜中的增塑剂和稳定剂。本研究旨在使用气相色谱-质谱法（GC-MS）研究 ESBO 从 PVC/PVDC 保鲜膜中的迁移情况。使用各种食品模拟物（水、4%乙酸、50%乙醇和正庚烷）评估 ESBO 对 PVC 和 PVDC 包装产品的特定迁移情况。所有测试样品均未将 ESBO 迁移到水中和 4%乙酸中。然而，在几种 PVC/PVDC 保鲜膜中，ESBO 被释放到 50%乙醇和正庚烷中，最大迁移水平分别为 38.4 ± 0.7 和 37.4 ± 0.8μg/mL。这些结果表明 ESBO 能够从 PVC/PVDC 保鲜膜中释放到亲脂性/油性食品中，其迁移应定期监测。
