Abstract

In this study, we aimed to improve the physical, mechanical and water-vapor permeability (WVP) properties of kappa-carrageenan (KC) films by including montmorillonite (MMT) nanoclay in the film-forming solution. To further improve these properties, the combined effect of Zataria multiflora Boiss essential oil (ZEO) and MMT was also investigated. The incorporation of MMT improved the physical and mechanical properties of KC film. Film made from KC alone had a tensile strength (TS) of 26.29 MPa, while the KC film with 10% nanoclay had a TS of 34.67. Further analysis was provided by X-ray diffraction and scanning electron microscopy that confirmed the dispersion of MMT in the KC matrix. It was also shown that the combined effect of nanoclay and ZEO significantly improved the TS and EB of KC films. ZEO decreased the WVP of the nanocomposite films; for example, 3% ZEO reduced WVP by around 78%. The antimicrobial activity of nanocomposite films was also studied using the overlay and vapor-phase methods; the films effectively inhibited the growth of five pathogens tested. Thus, the incorporation of both nanoclay and ZEO into KC films is a promising way to manufacture films with better mechanical, antimicrobial and WVP properties. (C) 2014 Elsevier B.V.
