Occurrence of meso/micro/nano plastics and plastic additives in food from food packaging.

Abstract

This chapter focuses on the occurrence of plastic constituents in food due to the contact with different types of plastic packaging, films and coatings. The type of mechanisms occurring during the contamination of food by different packaging materials are described, as well as how the type of food and packaging may influences the extent of contamination. The main types of contaminants phenomena are considered and comprehensively discussed, along with the regulations in force for the use of plastic food packaging. In addition, the types of migration phenomena and factors that may influence such migration are comprehensively highlighted. Moreover, migration components related to the packaging polymers (monomers and oligomers) and the packaging additives are individually discussed in terms of chemical structure, adverse effects on foodstuffs, health, migration factors, as well as regulated residual values of such components.
