Abstract	14 15 In the absence of a functional barrier, mineral oil hydrocarbons from printing inks and recycled 16 fibers tend to migrate from paper-based food packaging materials through the gas phase into dry 17 food. Concentrations easily far exceed the limit derived from the Acceptable Daily Intake (ADI) of 18 the Joint FAO/WHO Expert Committee on Food Additives (JECFA). Since estimation of long-term 19 migration into the food by testing at 40°C for 10 days is difficult, it seems preferable (and easier) to 20 use the mineral oil content in the paperboard. Evaporation experiments showed that hydrocarbons 21 eluted up to about n-C24 are sufficiently volatile for relevant migration into dry food: in worst case 22 situations about 80% migrate into the packed food. The extraction of the paperboard was optimized 23 to give good recovery of the relevant hydrocarbons, but discriminate against those of high 24 molecular mass which tend to disturb gas chromatographic analysis in on-line coupled normal 25 phase HPLC-GC-FID. Even though some of the relevant hydrocarbons had already evaporated, the 26 average concentration of
