- Combined effect of montmorillonite nanoclay (MMT) (3%w/w) and Origanum majorana essential oil (MO) (0.5, 1.0, and 1.5%v/v) on microstructural (SEM, TEM, and XRD), water sensitivity, barrier, mechanical, thermal, and antibacterial properties of sodium alginate (SA) was studied. Results showed that, addition of both MMT and MO reduced water solubility of SA film up to 47% while MO increased water vapor permeability of SA/MMT films. MO improved surface hydrophobicity of SA/MMT film but tensile strength tend to decrease when both MMT and MO (≥ 1%v/v) were added into film formulation. The nanocomposite film inhibited the growth of Escherichia coli, Listeria monocytogenes, Bacillus cereus, and Staphylococcus aureus at 1.5% MO concentration confirming the functionality of the films. Finally, combined application of MMT and MO could provide a tool for developing an active SA film with minimized side effects caused by the hydrophobic nature of the essential oil.
