Additives, Inks and Other Migrant Substances in Food Contact Materials
Advances in food packaging have revolutionized food safety. Current packaging materials protect food from external agents, facilitate transport, conserve desirable organoleptic properties and increase product shelf life. However, certain starting compounds or additives commonly used in the manufacture of food contact materials (FCMs) may remain unreacted in the FCM matrix and consequently migrate into food. Such migration phenomena may represent a potential food safety issue. This chapter discusses typical additives used in FCMs, mass spectrometric methods for the analysis of potential migrants and how these methods can help protect consumer health. Understanding the properties of these additives and their potential for migration is also important for selecting appropriate FCMs for specific purposes.
