BACKGROUND
The aim of this research was to understand the migration of bisphenols from can coatings into foods in the Chinese market.
RESULTS
The migration of bisphenols was studied in commercial cans from the Chinese market filled with four types of food simulant (FS), which were heated at 121 °C for 30 min and stored at 40 °C for 30 days. Only bisphenol A (BPA) and bisphenol A diglycidyl ether (BADGE) were found in the can coatings, and SimC (10% (v/v) ethanol/water) was the most suitable FS for their release. The levels of these bisphenols in 24 kinds of canned beer from Chinese markets were also investigated. The average concentrations of BPA and BADGE were 2.85 ± 0.79 and 0.38 ± 0.19 µg · L⁻¹ respectively, which were both lower than the EU limits, and their respective daily intakes were estimated at 0.015 and 0.0020 µg · kg⁻¹ body weight · day⁻¹. Besides, increasing storage temperature and time accelerated the release of bisphenols into FSs.
CONCLUSION
The present results provide some guidance to reduce the migration of bisphenols during the transport and storage of canned foods.
背景
本研究的目的是了解中国市场上罐装涂料中的双酚类物质向食品中的迁移情况。
结果
研究了中国市场上装有四种食品模拟物（FS）的商业罐头中双酚类物质的迁移情况，这些罐头在121°C下加热30分钟，并在40°C下储存30天。在罐装涂料中仅发现双酚A（BPA）和双酚A二缩水甘油醚（BADGE），且SimC（10%（v/v）乙醇/水）是最适合它们释放的食品模拟物。还调查了中国市场上24种罐装啤酒啤酒啤酒中这些双酚类物质的含量。BPA和BADGE的平均浓度分别为2.85±0.79和0.38±0.19μg·L⁻¹，均低于欧盟限量，其各自的每日摄入量估计分别为0.015和0.0020μg·kg⁻¹体重·天⁻¹。此外，储存温度和时间的增加会加速双酚类物质向食品模拟物中的释放。
结论
目前的结果为减少罐装食品运输和储存过程中双酚类物质的迁移提供了一些指导。
