Abstract In this work, active and edible films for food packaging were obtained by intensive mixing and compression molding of the wheat gluten (WG) glycerol-plasticized paste. Thyme essential oil (TEO, 10 and 15 wt.%) was incorporated as the active component microencapsulated in β-cyclodextrins (β-CD) and included directly into the biopolymer matrix for comparison. It was found that films incorporating microencapsulated TEO are more soluble in water (total soluble matter (dry method) of about 33% and 36.6% vs. 22.4% and 18.6%, for films containing 10% and 15% TEO, respectively) but less rigid than those obtained with free oil… More >
