The aptitude of a novel biodegradable material [wheat gluten/montmorillonite (MMT)] to be used as a food‐contact material was assessed with a focus on mass transfer from the film into foodstuff (migration). Special attention was paid to the impact of high‐pressure treatments and subsequent storage. Several aspects were treated: the migration of a model molecule (Uvitex OB), MMT migration, protein migration, and overall migration. The results showed that overall migration and protein migration were high; on the contrary, MMT and Uvitex OB migration was low or not detectable. No difference was found between the high‐pressure‐treated samples and the control, except for the migration of MMT. Two solid simulants (agar gel and Tenax) were also tested to emphasize the need of new migration tests adapted to water‐sensitive materials. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
