This part of this European Standard specifies methods for the determination of the monomer terephthalic acid in food simulants; distilled water, 3 % w/v acetic acid aqueous solution, 15 % v/v ethanol aqueous solution and olive oil and other fatty food simulants, simulants D, e.g. a mixture of synthetic triglycerides or sunflower oil or corn oil. The methods are capable of determining terephthalic acid in the food simulants at the level of the specific migration limit of 7,5 mg of terephthalic acid per kilogram of food simulants. NOTE This method was developed for the determination of terephthalic acid in 15 % v/v aqueous ethanol, as required by the regulations in force at the time the development work was carried out. However, this method, developed for 15 (v/v) aqueous ethanol, should be applicable to the determination in 10 (v/v) aqueous ethanol.
