Migration of the n-alkanes from paraffin coated paper was evaluated. Paraffin coating was applied to Kraft paper with an automated coating machine. Grammage was controlled by weighting
according to the wax manufacturer’s specifications. Worst case scenario was chosen for this study, thus a grammage between 20 and 25 g m ?2 was selected. A round sample of 19.6 cm 2 (5 cm of diameter) of paraffin paper was cut and placed in a Petri dish. A slice of cheddar cheese of about 2 mm of thickness and 19.6 cm 2 of area (4.5 g) was placed in direct contact with the upper side of the paraffin paper. According to the recommended use of the material (refrigerated but not frozen), migration testing was performed at 20 ± 0.1 ?C in an ATP Line KB incubator (Binder, Tuttlingen,Germany
