Preparation and characterization of antioxidant edible chitosan films incorporated with epigallocatechin gallate nanocapsules.Antioxidant edible films based on chitosan hydrochloride (CHC) and epigallocatechin gallate (EGCG)-loaded nanocapsules (NCs) were developed.  The CHC films incorporated with NCs were prepared by a casting method in three different proportions.  The addition of NCs to CHC films increased their tensile strength (TS) and the percent elongation at break (%E).

Preparation and characterization of antioxidant edible chitosan films incorporated with epigallocatechin gallate nanocapsules.Antioxidant edible films based on chitosan hydrochloride (CHC) and epigallocatechin gallate (EGCG)-loaded nanocapsules (NCs) were developed.  Meanwhile, the mechanical and color properties, optical transmittance, EGCG release profile and antioxidant activity were also determined.  EGCG was rapidly released into food simulant although the concentration fluctuates over time.

The CHC films incorporated with NCs were prepared by a casting method in three different proportions.  The addition of NCs to CHC films increased their tensile strength (TS) and the percent elongation at break (%E).  Lightness was significantly decreased in the NCs embedded films compared to controls, which in turn led to high antioxidant activity and excellent barrier properties against visible light.
