Bisphenol A (BPA), a synthetic chemical which has raised concerns due to its potential toxicological effects on humans, has been widely detected in canned and non-canned meat and meat products. This study estimated BPA migration from packaging to non-canned and canned meat products by developing two probabilistic models. BPA concentration data in packaging materials were collated, including polyethylene terephthalate, polyvinyl chloride, epoxy-based coatings, and polyester-based coatings. Migration ratios were calculated from migration tests of BPA molecules moving from packaging to food simulants. The predictive model revealed that the BPA migration concentration from packaging ranges from 0.017 to 0.13 (5th-95th percentile) μg kg with a simulated mean of 0.056 μg kg in non-canned meat products. This is in stark contrast to the simulated mean of 134.57 (5th-95th percentile: 59.17-223.25) μg kg for canned meat products. Nevertheless, plastic packaging was estimated to contribute only 3 % of BPA levels in non-canned meat products. The sensitivity analysis showed that the contact area of meat products with films is the most sensitive parameter of the plastic packaging migration model. It is concluded that plastic packaging may not be the only or dominant source of BPA in non-canned meat products.
双酚 A（BPA）是一种合成化学物质，由于其对人类潜在的毒理学影响而引起关注，已在罐装和非罐装肉类及肉类产品中广泛检出。本研究通过建立两个概率模型来估计包装向非罐装和罐装肉类产品中迁移的双酚 A。收集了包装材料中聚对苯二甲酸乙二醇酯、聚氯乙烯、环氧基涂料和聚酯基涂料等的双酚 A 浓度数据。通过双酚 A 分子从包装向食品模拟物迁移的迁移试验计算迁移率。预测模型显示，包装中双酚 A 的迁移浓度范围为 0.017 至 0.13μg/kg（第 5 至 95 个百分位数），模拟均值为 0.056μg/kg，而非罐装肉类产品。相比之下，模拟罐装肉类产品的双酚 A 浓度均值为 134.57μg/kg（第 5 至 95 个百分位数：59.17-223.25μg/kg）。然而，塑料包装估计仅占非罐装肉类产品中双酚 A 水平的 3%。敏感性分析表明，肉产品与薄膜的接触面积是塑料包装迁移模型中最敏感的参数。结论是，塑料包装可能不是非罐装肉类产品中双酚 A 的唯一或主要来源。
