Abstract
Lately food packaging has gained a widespread importance in food safety due to the possibility of migration of chemicals from food contact plastic materials. In this context the project FOODMIGROSURE (QLRT-2001-2390) aims to find tools which allows to estimate consumer exposure to these chemicals. In order to carry out a compilation of the available information on analytical methods to determine model migrants in selected foodstuffs, an extensive bibliographic review was done. Model migrants of different chemical structures, polarities, lipophilicity and molecular weight have been selected in this project: Styrene, Bisphenol A, 1-octene, Limonene, Di-isopropyl naphthalene (DIPN), Laurolactam, Triacetin, Tri-n-butylacetyl citrate (ATBC), BHT and Triclosan. Due to the complexity of food samples, procedures more broadly used with food simulants don't seem the most appropriate to evaluate the migration of these compounds in foods. Any protocol drawn up on the basis of the literature and general analytical principles and experience is necessarily a tentative proposal requiring exhaustive evaluation and preliminary experiments. Important properties of these migrants such as ultraviolet and fluorescence were evaluated to help to decide the approach for the development of analytical methods that allow determining these compounds in foodstuffs. Several techniques were also checked (HPLC, GC). Extraction experiments with acetonitrile from olive oil were carried out in order to obtain more information about the possible behaviour of these migrants in concrete cases.
