Natural deep eutectic solvents based on choline chloride as a green plasticizer to produce chitosan based films

There is a worldwide interest in replacing the use of oil-based synthetic plastics with biodegradable, nontoxic packages. The
development of new package products can benefit various industrial activities, particularly the production, distribution
and commercialization of foods. Chitosan (CH), a polysaccharide derived from chitin, is a promising biopolymer to be used
for this issue, since chitin is the second most abundant polysaccharide in nature and can be obtained as a reject of the seafood
industry in coastal regions, inland or even associated to shrimp aquaculture production. Besides, the environmental benefits
related to the removal of seafood residues and the replacement of petroleum-based-packages, chitosan can be considered an
active package material, since its physicochemical properties, such as molecular weight and degree of deacetylation, can confer
special activities to chitosan, including antimicrobial activity, which can be very useful in food packing. We present previously
unexplored approach based on the use of natural deep eutectic solvents (NADESs) as potential biodegradable plasticizer.
Specifically, we report the use of different NADESs as precursors for the fabrication of transparent chitosan films prepared by
compression molding. Film structure was studied with FESEM and the optical, water permeability and mechanical properties
were also evaluated. Significant differences were verified in the behavior of the biofilms under the different experimental conditions.
