ABSTRACT

Edible films were successfully developed through a new patent pending method. Seaweed (Kappaphycus alvarezii) was directly used to prepare film forming solutions without prior extraction into carrageenan. Cinnamomum zeylanicum essential oil (CEO) with different concentrations was added into the film forming solutions before casting. The effect of CEO on the physical and mechanical properties of films were studied. The thickness of films was not affected by the CEO incorporated concentration. Results obtained showed that films incorporated with CEO reduced light penetration compared to the film without CEO. The ability to block light penetration improved when the CEO concentration increases. Solubility, tensile strength and water vapour permeability for the films incorporated with CEO were lower than the film without CEO. Furthermore, the elongation at break was increased when the amount of CEO increased. This study reveals that CEO is potentially a good natural preservative for the preparation of seaweed-based edible film in food applications.

Key words: Edible films, seaweed, cinnamon essential oil, physical and mechanical properties
