Case 2: Nanotechnology trends to enhance biopackaged food, food quality and safety Jose M. Lagaron Novel Materials and Nanotechnology Group, IATA, CSIC, Avda. Agustín Escardino 7, 46980 Paterna (Valencia), Spain E-mail: email@example.com In this presentation, the current situation of novel nanobiostructured packaging materials is described, together with the global challenges to be faced and the possible strategies to overcome some of the pending issues in this exciting and potentially world changing research and development. Introduction In the last decades there has been a significant increase in the amount of plastics being used in various sectors, particularly in food packaging applications. In fact, the largest application for plastics today is packaging, and within the packaging niche, food packaging amounts as the largest plastics demanding application. This is so, because plastics bring in enormous advantages, such as thermosealability, flexibility in thermal and mechanical properties, and they permit integrated processes, lightness and a low price. However, polymers do also have a number of limitations for certain applications when compared with more traditional materials like metals and alloys or ceramics. The chief limitation being their inherent permissiveness to the transport of low molecular weight components, which leads to issues such as food oxidation by penetration of oxygen, migration of toxic elements from the plastic and scalping of food components on the packaging with the consequent losses in food quality and safety attributes. From these, the potential migration of polymer constituents and additives is perhaps the most widely recognized issue regarding packaged food safety. In spite of this, plastic materials continue to expand and replace the conventional use of paperboard, tinplate cans and glass, which have been typically used as monolayer systems in food contact materials. Initially, most plastic packaging were made of monolayer rigid or 45
