Migration of Ethylene Glycol from Polyethylene Terephthalate Bottles into 3% Acetic Acid

Journal of AOAC INTERNATIONAL, 1980
Abstract Migration of ethylene glycol (EG) from polyethylene terephthalate (PET) bottles into the food simulant 3% acetic acid was studied using 32 fluid oz PET bottles filled with 3% acetic acid and stored at 32° C for 6 months. Final concentration of EG in the 3% acetic acid migration solution was about 100 ppb, which is equivalent to ...
