Increased “global” migration into food simulants has been described as a consequence of irradiation, particularly with fatty media; development of off-odors and taint transfer into food simulants have been observed with various plastics. Additives, especially antioxidants, are destroyed during irradiation, and increased “specific” migration values have been observed under certain circumstances. Organotin stabilizers in PVC are ultimately degraded to SnCl4, and increased migration of tin compounds was observed after gamma irradiation. Degradation products of phenol antioxidants, that were also found as migrants, have only recently been identified; some of these structures seem to be radiation specific.
