title: Release of bisphenols from can coatings into canned beer in China market.
abstract: 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.
  
  
  CONCLUSIONS
  The present results provide some guidance to reduce the migration of bisphenols during the transport and storage of canned foods.
