Biomimetic Water Vapor Barrier Composite Films

Abstract:

A new type of barrier composite film, imitating the structure of apple peel, was prepared in this study. Paraffins, sodium alginate, stearic acid and carboxymethyl cellulose were used to mimic the wax layer, cuticle, pectin layer and single-cell layer of the apple peel, respectively. Different factors have been considered to determine their effects on the water vapor permeability of the films, such as drying temperature, cross-linking agents and thickness of the membranes. The results showed that composite films showed good barrier property in the condition of drying temperature of 60°C and cross-linking agents concentration of 15 mg/ml. The imitating cutinmembrane layer played an important role on resisting water vapor.
