Bicompatible Metal-Organic Framework for Functional Packing of Food Products

Biocompatible metal-organic framework [Zn 4 (GA) 4 (H 2 O) 4 ]·4H 2 O (H 2 GA is glutamic acid) is tested as a “container” with bioactive hydrophobic components of jasmine essential oil for the preparation of functional composite materials based on a hydrocolloid matrix containing kappa-carrageenan and hydroxypropyl methylcellulose. The prepared composite film coatings exhibit high antimicrobial and antioxidant activities in the model experiment with a long-term storage of fruits, which indicates broad prospects for the practical use of these materials as an active packing of food products.
