Abstract:

Differential testing of food content represented in the past one of the usual methods employed to highlight the possible migration of ions or molecules from food contact materials into food. However, some of the methods developed recently offer the possibility to investigate the levigation of packaging compounds through different organic coatings into foods. The aim of this paper is to present a novel method for testing the inside coating layers, namely electrochemical impedance spectroscopy (EIS), in order to reveal the interactions that may occur between foods, food additives and the packaging materials. The experiments were conducted on two different samples, evaluated within six month time interval. From the Nyquist plots, applying a circular regression procedure, one was able to determine the values of the charge transfer resistance (R2), a characteristic element for the structural and compositional consistency of packaging materials. One has gone further by calculating an equivalent interaction distance (eid) and a medium equivalent interaction distance (meid) and by doing these one has now succeeded to evaluate not only qualitatively but also a quantitative index for quantifying the above said interactions. Keywords: Electrochemical impedance spectroscopy, charge transfer resistance, polymer coatings, food cans, equivalent interaction distance
