Fig. 2 shows the XRD patterns of pure chitosan (CG0) and
chitosan-based composite
films (CG1, CG2, CG3). All the
films
produced a diffraction pattern of a semicrystalline to an
amorphous phase. CG0 showed characteristics peaks of chitosan
films around 2u = 11 and 18 [20]. With the addition of GFSE into
pure chitosan
films, the intensity of XRD peaks decreased,
displaying a diffraction pattern of an amorphous phase with the
background raised at around 2u = 20, demonstrating the behavior
of GFSE within the matrix of the
films. The intensity of the XRD
GFSE chitosan-based
film (CG1), day 9 for the sample packed with
1.0% v/v GFSE chitosan-based
film (CG2) and subsequently on day
10 for the sample packed with 1.5% v/v GFSE chitosan-based
film
(CG3). Results from the preliminary antifungal activity evaluation
indicated that the incorporation of GFSE into pure chitosan
film
improved the antifungal properties of the
film and significantly
retarded the proliferation of fungal on bread samples.
