Preparation, characterization and anti-aflatoxigenic activity of chitosan packaging films incorporated with turmeric essential oil.
Int J Biol Macromol. 2019 Jun 15; 131:420-434.IJ

Abstract

Here, we studied the preparation, characterization, anti-aflatoxigenic activity, and molecular mechanism in vitro of chitosan packaging films containing turmeric essential oil (TEO). First, we took the mechanical properties as the evaluation Index, screened for the optimum preparation conditions of packaging films with 1.5 μL/cm2 TEO using single factor and orthogonal experiments, and characterized the film properties. We found that the addition of TEO affected the microcosmic structure of films and advanced water resistance capacity. In addition, we investigated the inhibitory effects of pure chitosan films and packaging films containing 1.5 μL/cm2 or 3.0 μL/cm2 TEO on the growth and conidial formation of Aspergillus flavus (A. flavus, CGMCC 3.4410), as well as the accumulation of aflatoxin over the course of seven days. We found that the packaging films possessed a prominent antifungal activity on A. flavus. Finally, we discuss preliminary results surrounding gene expression of packaging films which inhibit aflatoxin biosynthesis. The expressions levels of 16 genes related to aflatoxin biosynthesis were found to be either completely or almost completely inhibited. Therefore, the addition of the natural antifungal agent TEO in chitosan packaging films represent a remarkable method to significantly promote the development and application of antifungal packaging materials.
