Besides permeability and mechanical integrity, wettability is another key factor to ensure effective film products, whereas all these factors should be optimized. Effective coating is dependent upon spreading coefficient (or wetta- bility) versus the surface properties of the fruits, in particular the dispersive component of the fruits’ surface tension (Cerqueira et al., 2009). Blending is also an approach to improve coating properties through the possible synergis- tic effects of the two components. For instance, blending of 0.5% galactomannans (a new natural product) and 1.5% collagen with an addition of 1.5% glycerol resulted in the decrease of gas transfer rate in mango (Lima et al., 2010). Composite films or coatings have also been developed to replace synthetic commercial waxes, for example, optimized locust bean gum (LBG)-lipid composite coatings for man- darins (Rojas-Argudo et al., 2009).
