2.3. Coating and films preparation
Coating formulations were prepared under a completely randomized design with factorial arrangement, where factors, A
= chitosan concentrations of: 0.5, 1.0 and 1.5% (w/v); B = glycerol concentrations of: 0.5, 1.0 and 1.5% (v/v); C = Tween 80 concentrations of: 0, 0.1 and 0.2% (w/v) were studied (Table 2).
