Odor-defeating plastic film for food packaging

Packaging and storage of odorant food products is challenging, and the concentration of odors may reach unbearable levels for the human olfactory system.
Researchers at Stockholm University in Sweden identified zeolites of MFI-type, ZSM-5, and silicalite-1 as highly efficient adsorbents for adsorption of light thiols. A combination of high thiol removal performance and mechanical stability suggest zeolite− cellulose nanofibrils composites as a potential candidate for use in active packaging material where the package contents, for example, fruits, foods, and vegetables release considerable concentrations of odors. An article about the research is published in Applied Materials & Interfaces.
