Acidic food simulant. The quantification of overall migration
was based on the procedures set forth in EN 1186-1 and EN 1186-3
(CEN, 2003; CEN, 2002). The methodology to quantify overall
migration in acidic simulant consists of contact of the sample with
extraction solutions for certain times and temperatures that
simulate their actual condition of use. The residues of overall
migration were determined by the difference in weight after the
contact and evaporation of the solutions on an analytical scale with
0.01 mg accuracy.
