Safety Assessment and Migration Tests

subject

description

This chapter outlines (i) the advances to reduce the uncertainty in nanomaterials (NMs) determination; (ii) the results from migration experiments conducted with nano-clay, nanosilver, and other nanomaterial-containing polymers; and (iii) the different established protocols for risk assessment that ensure consumer's safety. The text starts highlighting the need of an understanding of potential exposure via migration into food and a deeper knowledge of the interaction of NMs with food constituents and their effects upon ingestion. The chapter covers the ability of the analytical techniques utilized to detect nanoparticles per se in food simulants. In addition, the results of the application of European standardized migration test to establish migration of NMs constituents or the nanoparticles themselves from polymer nanocomposites into food or food simulants are described. A full discussion of the established protocols for NMs in food packaging safety assessment is included to bring together the different aspects into an integrated whole.
