Production and Evaluation of Properties of Edible Starch Film Containing Bene (Pistacia atlantica) Gum Essential Oil

Abstract

Pistacia atlantica is the dominant species of Pistachio in Iran. Mastic Gum is a resinous gum, which is called Saghghez in Iran. Firstly, the essential oil (EO) of Pistacia atlantica gum was extracted by hydrodistillation method, then the starch film containing Pistacia atlantica essential oil at 0, 0.5, 1 and 2% (V/V) were prepared applying casting method and their physicochemical, mechanical, permeability properties were evaluated.The results showed that the incorporation of EO caused a significant increase (PP<0.05). In the films containing EOs, increasing the concentration of essential oils did not cause a significant effect on oxygen permeability. To study the microstructure of the films, further analysis was provided by the scanning electron microscope (SEM), the results of this test indicate the production of uniform and without crack films and also confirming the results of the permeability tests.
