Migration analysis of epoxidized soybean oil and other plasticizers in commercial lids for food packaging by gas chromatography-mass spectrometry

Résumé

A modification of the well-known method developed by Castle et al for the analysis of Epoxidized Soybean Oil (ESBO) is proposed in order to simplify the analysis and reduce the time and reactive consumption. The proposed modifications, particularly the elimination of the internal standard, resulted in a simpler, faster and more economical method. A complete analytical validation, including evaluation of the main analytical parameters, such as detection and quantification limits, linearity, working range, precision, accuracy and selectivity, was carried out. The obtained data proved the suitability of the proposed method for the determination of ESBO in polymer matrixes. In this way, a specific migration study for ESBO in different food simulants (fat and aqueous) was carried out by applying the proposed method to PVC materials prepared with known amounts of ESBO, as well as some commercial lids. High migration levels of ESBO for fat simulants were found. In the case of commercial lids, in addition to ESBO, some other plasticizers such as citrates, adipates and sebacates were found and quantified to establish their migration in different conditions.
