Special Report No. 08-02: The Potential for Migration of Anthraquinone from Unbleached Linerboard

Experiments were conducted to assess the potential of anthraquinone possibly contained in food packaging such as pizza boxes to migrate into food, specifically just-cooked pizza crust brushed with vegetable oil. Briefly, pizza dough was purchased from a local pizzeria and baked according to instructions. After baking and while still hot, heated vegetable oil was brushed on the bottom of the baked crust, the crust placed on a piece of unbleached kraft linerboard and the crust-linerboard wrapped in foil.
