Hybrid membrane containing cyclodextrin nanosponges for innovative active packaging

Food packaging has multiple scopes i.e.: protection, communication, containement etc. but more recently other performances were requires such as to reduce preservatives and increase food safety. Actually active packaging can be intended as an innovative packaging that allows the extention of the shelf life of the products ameliorating or preserving their original qualities. Organic polymers are often the material of choice for these applications. Nevertheless, their properties not always meet the requirement of the industries. More recently, the incorporation of certain components in the packaging films can favour the release or the adsorption of the desired substances from or into the packaged food so prolong the shelf life and sustain the quality, the safety and sensory characteristics of the food.
