However, although the new bilayer edible coating somewhatincreased fruit firmness, it was not very effective in reducing water-vapor permeability and weight loss (Fig. 2). In this respect, it isknown that polysaccharide-based as well as protein-based ediblecoatings do not form efficient water-vapor barriers (Valencia-Chamorro et al., 2010; Dhall, 2013). Moreover, it appears thatalso other proposed edible coatings developed for citrus were notvery efficient in preventing weight loss during storage (Navarro-Tarazaga et al., 2008; Rojas-Argudo et al., 2009; Valencia-Chamorroet al., 2011; Contreras-Oliva et al., 2012).
