“…A neutron activation method developed for the analysis of HDPE, LDPE, PP, PET, and PS food‐contact plastics provides for determination of over 50 elements at a concentration of below 1 mg/kg (Thompson and others 1996). This technique has now been extended to study migration from food‐contact materials into standard food simulants (olive oil, acetic acid, ethanol, and water).…”

Food packaging, although an integral part of the food chain, has a major drawback in that, often, the packaging material interacts with the flavor constituents of the food, causing either a selective or an extensive loss of desirable food flavors or absorption of undesirable off-flavors from the packaging material, thereby resulting in an eventual loss of quality of the packaged food item. The process is called "scalping" and is of great concern to the food industry, which is always looking out for new avenues in "packaging solutions" for its final product quality needs. The review highlights the various attributes of the scalping process, explores approaches to the reduction of the manifested undesirable effects, and covers other relevant aspects.

A radiotracer method was applied to the measurement of inorganic contaminants migrating into food. The method was applied to the study of 10 samples of recycled paper and board. The only elements detected in the static migration test were zinc and iron, at concentrations close to the detection limit. Samples of rice, oats, custard powder, mushrooms and fries showed that traces of these elements had migrated from the packaging. The migration was limited to less than 1%, with the exception of the mushrooms, where the decomposition of the food had resulted in a 12.5% transfer of zinc from the mushroom bag after 8 days, equivalent to migration of 0.022 mg dm(-2). Shaking had no effect on migration, except in one case of custard powder where migration occurred at a level equivalent to 0.002 mg dm(-2). The maximum migration determined in the present study was 4.8 microg zinc and 2.6 microg iron, which is negligible when compared with the recommended daily intakes of 15 and 14 mg, respectively. When Tenax was tested as a food simulant, no zinc was detected (< 0.001 mg dm(-2)), although slight migration (0.001 mg dm(-2)) occurred into food.

“…Em relação à segurança alimentar, é importante destacar que o plástico utilizado na confecção das embalagens pode conter constituintes inorgânicos provenientes do resíduo catalítico de seu processo de fabricação, das tintas de impressão ou ainda dos aditivos utilizados no processo, os quais podem migrar para o conteúdo das embalagens (Thompson et al, 1996;Crompton, 1979).…”
