Metal nanoparticles and carbon nanotubes—perfect antimicrobial nano-fillers in polymer-based food packaging materials
TLDR
In this article, the most important questions related to metallic nanoparticles in food packaging (health and environmental considerations, performance, and costs), with the special emphasize on their applicable and toxicological properties.Abstract:
Advances in food packages are oriented to obtain improved quality and safety. Incorporation of antimicrobial compounds in the form of nano-fillers into polymer-based food packaging materials has received considerable attention. These active packages are applied to extend shelf life while maintaining nutrition quality and ensuring microbiological safety. Antimicrobial nanocomposite films are desirable for application in the food industry due to their advantages: structural integrity and barrier properties imparted by the matrix, as well as the antimicrobial properties resulting from impregnated antimicrobial agents. Metal nanoparticles, metal oxide nanomaterials, and carbon nanotubes are mostly used in developing antimicrobially active polymer materials. This chapter deals with some of the most important questions related to metallic nanoparticles in food packaging (health and environmental considerations, performance, and costs), with the special emphasize on their applicable and toxicological properties.read more
