Abstract

Research on preparation of edible film from breadfruit starch and alginate incorporated with essential oil of attarasa leaves  (Litsea cubeba Lour Pers.) has been done.  The film was evaluated of their thickness, tensile strength, elongation at break, water vapor transmission rate (WVTR) and microstructural properties by Scanning Electron Microscopy (SEM). Incorporation of the oil increased  thickness of film from 0,033 mm to 0,036 mm, tensile strenght from 32,8 to 37,0 MPa, elongation at break from 48,92% to 50,43%  but water vapor transmission rate (WVTR) decreased from 142,9 g/m2.hour to 120,3 g/m2.hour. However SEM analysis showed that the surface microstructural of the film was more rough and solid compare with film without incorporation of essential oil.

 

Keywords : attarasa leaves,  essential oil, breadfruit starch,  alginate,  edible film
