Determination of bisphenol a migrating from canned food and beverages in markets

The determination of bisphenol A (BPA) in foods and beverages sold in Turkish markets was carried out using high performance liquid chromatography. In this research, foods packed in packages with an inner surface covered with plastic film, such as milk, fruit juice, cream, pudding and tuna samples were used. Furthermore, foods in glass jar and metal cans such as green peas, garniture, corn, tomato paste, pepper paste, pickles, mushroom and bean samples were also used. BPA concentrations were 21.86 +/- 0.80-1858.71 8.24 mu g kg(-1), for canned foodstuffs, 36.48 +/- 0.95-554.69 +/- 3.18 mu g kg(-1) for foods in paper box, not detected - 399.21 +/- 3.26 mu g kg(-1) for foods in glass jar. The change in the amount of bisphenol A in all of these food, based on expiration date, the amount of glucose and sodium chloride in it has been determined. We see that in these kind of food the amount of bisphenol A increases with an increase in the amount of glucose, NaCl and expiration date. (C) 2013 Elsevier Ltd. All rights reserved.
