The potential of food packaging components to migrate into food is an important health concern. Perfecto Paseiro Losada and his group at the University of Santiago de Compostela, in Spain, have been investigating the migration kinetics and actual migration of such compounds into a variety of types of food. They also have been carrying out studies to estimate dietary exposure. Paseiro recently spoke to LCGC about this work.
