Investigations into the potential degradation of polycarbonate baby bottles during sterilization with consequent release of bisphenol A

摘要

Twenty-four brands of plastic baby feeding bottles were purchased and all were found to be made of polycarbon- ate. Taking a batch of one representative sample, the polymer was tested for stability and possible release of bisphenol A following domestic practice of sterilization. Sterilization was by alkaline hypochlorite, steam, or Washing in an automatic dishwasher at 65 deg.C with Detergent. A total of 20 cycles of sterilization and Subsequent food use were performed for each of the Three procedures. Bisphenol A migration was in all Cases not detectable in infant feed using a very sensitive Method of liquid chromatography with fluorescence Detection with a 0.03 mg/kg detection limit.
