The development of packaging material added by nano-scaled structures is an area of application of nanotechnology in the food industry. Nanoparticles (NPs) have been widely demonstrated to improve technological properties of materi als by increasing their mechanical resistance and barrier capacity, to mention a few. However, being an innovative technology, there are still gaps in knowledge, especially those related with the toxicity driven by the NPs' migration to pack aged foodstuff. In this chapter, this issue is discussed focusing on three aspects: Characterization techniques of the migration of NPs into food matrices, toxicolog ical matters, and regulatory issues. Characterization techniques address the chal lenging characterization of NPs after their migration from food contact materials to food matrices. Toxicological aspects will cover the safety issues related with NPs diffused from packaging to food. Finally, current regulation on food contact materials and migration assays will be summarized to assist the readership in this matter.
