reported that oleic acid addition in chitosan-based coatings reduced the WVR, behavior also observed in this study. However, some authors reported different results, which showed that the interactions between the ingredients used in the coatings formulations led to different barrier properties. Navarro-Tarazaga, Massa, and PérezGago (2011) observed that the water vapor permeability of carboxymethyl cellulose and oleic acid-based films has significantly increased by glycerol addition. Garcia et al. (2010) concluded that higher cassava starch concentrations lead to higher water vapor
resistance of edible coatings applied in strawberries. However, the authors observed that polysaccharides-based coatings without lipids did not promote a large increase in water vapor resistance, due to its hydrophilic nature. Auras, Arroyo, and Selke (2009) also observed that water vapor permeability of cassava starch films have increased as a function of glycerol and beeswax content.
