The migration of acetyl tributyl citrate (ATBC) and di-butyl sebacate (DBS), which are used as additives in polyvinylidene chloride (PVDC) film, into fatty food simulants was studied. The fatty food simulants used in the tests were n-heptane, an edible oil, and three kinds of model fatty foods.<br> The additives which migrated from the PVDC film into the fatty food simulants were extracted by solvents and determined by gas chromatography.<br> The evaporating residue was also measured with the use of n-heptane, then the total migration amount was calculated.<br> The results may be summarized as follows:<br> (1) It was ascertained that, when n-heptane was used as a fatty food simulant, the total migration amount corresponded to the total quantity of additives extracted by n-heptane.<br> (2) Upon heating at 90°C for 90 minutes, 30-160μg/g of ATBC and 45-290μg/g of DBS migrated from PVDC film into the model fatty foods. When n-heptane was used, migration of ATBC and DBS upon heating at 90°C for 90 minutes was 2.9-11.2 times and 1.5-8.3 times the above values, respectively.<br> (3) The total migration amount into n-heptane upon heating at 150°F (about 66°C) for 120 minutes was 1.6-5.1 times that into model fatty foods upon heating at 120°C for 20 minutes.<br> (4) In conclusion, the migration of additives from PVDC film into model fatty foods is small. Assuming that a person weighing 50kg takes 100g per day of foods containing these additives, the quantities of such additives which remain in his body are below the ADI (Ac-ceptable daily intake for man) value calculated by MCCOLLISTER.
