Migration and Sensory Changes in Packaged Food Products

The migration phenomena involving packaging materials that lead to sensory changes in food, cosmetics and other products have not been as widely investigated and monitored as those relevant to safety aspects. The main basic occurrences and the theory behind the migration, however, are substantially the same; the analytical approaches are also similar and in both cases the effectiveness of mass spectrometry is fundamental to solving problems and understanding mechanisms and risks. In this chapter, the adverse effects, denoted “sensory changes,” caused by migration phenomena are discussed and the general theory of migration via diffusion phenomena is summarized, with reference to the alteration of perceivable sensory attributes and to commonly used packaging materials. Recent findings and the main analytical procedures used in this particular field are briefly presented.
