  • Title: Tailoring Functional Chitosan-Based Composites for Food Applications.
    Author: Nunes C, Coimbra MA, Ferreira P.
    Journal: Chem Rec; 2018 Jul; 18(7-8):1138-1149. PubMed ID: 29517853.
    Abstract:
    Chitosan-based functional materials are emerging for food applications. The covalent bonding of molecular entities demonstrates to enhance resistance to the typical acidity of food assigning mechanical and moisture/gas barrier properties. Moreover, the grafting to chitosan of some functional molecules, like phenolic compounds or essential oils, gives antioxidant, antimicrobial, among others properties to chitosan. The addition of nanofillers to chitosan and other biopolymers improves the already mentioned required properties for food applications and can attribute electrical conductivity and magnetic properties for active and intelligent packaging. Electrical conductivity is a required property for the processing of food at low temperature using electric fields or for sensors application.
