Three lipids (beeswax, palmitic acid and stearic acid) and a hydrophilic film (soybean protein-isolate/carboxymethyl cellulose film) were selected as a model to inspect the relation between the lipid state and barrier properties. The free-lipid ratio of composite films was the best indicator for the transparency rather than the moisture barrier. The free-lipid content/total-lipid content had the highest negative correlation factor with the moisture barrier. Hence, raising free-lipid ratio was effective to improve the moisture barrier of hydrophilic films.
