3.2. Characterization of chitosan films
Table 3 shows the humidity, solubility and solids gain values of
elaborated films from chitosan-Tween 80 solution and chitosan lipid
emulsion, respectively. Prodpran, Benjakaul, and Artharn
(2007) studied the effect of the film composition on its solubility
and found that the chitosan addition in films-forming solutions
based on proteins, decrease the film solubility in certain way when
the chitosan concentration was increased, independently of presence
or not of oil, which could due to interactions protein/chitosan
or between chitosan molecules (Giancone, 2006). Oil addition in
the preparation of chitosan lipid emulsion increased the film solubility
due to oil drops can insert into matrix film, decreasing the
crossed links between proteins or interactions between chitosan
molecules (Prodpran et al., 2007). On the other hand, the solids
gain from syrup was similar in both films.
