Special Issue Information

Dear Colleagues,

Polymer nanocomposites are prospective and rapidly developing materials. They have potential uses in many applications, including in human and animal nutrition.

This Special Issue deals with research into polymer nanocomposites in animal and human nutrition. Polymer nanocomposites are used to facilitate the active transport of essential nutrients into the gastrointestinal tract (GIT). Other purpose can include the targeting of antibiotics or natural antibiotic compounds to their required sites. However, the nanotoxicology of polymer nanocomposites must be carefully considered in terms of nutrition. Moreover, further investigations should be focused on their influence on metabolic processes.

In this Special Issue, in vivo and in vitro studies are welcomed.

Spoilage of fish due to microbiological activity is one of the biggest problems found by producers to take fresh fish products to customers. It is necessary packaging improvements to be able to increase fish shelf life and, thus, be able to travel further and to keep product freshness longer at customer’s houses. In the present work, a new material is developed for fish packaging in modified atmosphere (MAP). This material is poly(ethylene terephathalate) (PET) extruded with a polyamide (PA) nanocomposite containing nanosepiolite. Here, it is shown the production procedure from laboratory to industrial scale. Permeability to oxygen and impact mechanical properties results are shown for different samples, both at laboratory and industrial processes. At the end, a material composition is chosen to produce the finale tray which will contain the sliced sea bream. Microbiological analysis is done over the packed fish, resulting is a lower microbiological count compared to a PET control sample. This means that shelf life of pack sea bream could increase from 2–4 to 7–9 days, which is very important for both producers and customers. On the other hand, trays obtained comply with European regulations in food contact materials (FCM) and, overall, they are suitable for food packaging materials. Full article
