Preparation of Edible Films Made from Chitosan with Pomegranate Peel Extract and Study Its Barrier, Mechanical and Antioxidant Properties

The goal of this work was to evaluate the effect of adding extract of Pomegranate peels (PPE) on the mechanical, reservation and antioxidant properties of edible chitosan films. The findings showed that the chitosan film, supported by pomegranate peels, possessed distinctive properties, as the thickness, tensile strength, elongation, oxygen permeability, and permeability of water vapor and solubility were 60 µm, 27.6 (Mpa),18.3%,30.13(ml / m²* day), 2.91(g.mm/day.m²KPa), 23.12% respectively, whereas in the control film they were 30 µm, 19.2 (Mpa),10.6%, 60.47(ml / m²* day), 2.30(g.mm/day.m²KPa), 26.50% respectively. Edible films incorporated with Pomegranate peels extract showed an antioxidant activity of 66.42% compared to the standard antioxidant BHA (Butylated hydroxyl anisole) and Ascorbic acid which were 27.44% and 80.54%, respectively.In respect to the optical proprieties the ?E value of control film samples was 8.7%,and (L, a, b) (26.46,40.01, 2.02) respectively, while for the supported Sample ?E was 26.37% (L, a, b) (72.24,1.09,5.30) respectively.
