Consumer exposure to bisphenol A (BPA) from consumption of canned soft drinks is low, claims a study published in the Journal of Agricultural and Food Chemistry.
The study, which evaluated the levels of BPA in canned drinks sold in Canada, indicated that while most of the drinks analysed contained BPA, the levels present were such that exposure to the packaging chemical was minimal.
According to the study, BPA is used to produce bisphenol A diglycidyl ether (BADGE), the inside coating of food and beverage cans.
The scientists claim that residual amounts of BPA can be present in BADGE as a result of incomplete reaction and that BPA and BADGE can migrate from can coatings especially at high temperatures.
Studies have found that BPA is a potential endocrine disruptor that mimics the action of estrogens, while recent UK research found that higher concentrations of the chemical in urine were linked with heart disease, type 2 diabetes and liver enzyme abnormalities.
