摘      要：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 *** essential oil(TEO,10 and 15 wt.%)was incorporated as the active component microencapsulated inβ-cyclodextrins(β-CD)and included directly into the biopolymer matrix for *** 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(elastic tensile moduli of 6.9 and 3.1 vs.9.9 and 6.8 MPa,for films containing 10%and 15%TEO,respectively),although the water vapor permeability of the former is lower(4.9510−9 and 6.2910−9 vs.8.8510−9 and 11.1310−9 g/Pa*s*m,for films containing 10%and 15%TEO,respectively).Active films containing both free and encapsulated TEO inhibited gram(+)as well as gram(−)bacteria and exhibited enlarged antioxidant properties,with the latter presenting slightly better *** addition,encapsulation slowed the release rate of TEO from the films,allowing the bioactive to remain active in the film for much ***,the present work revealed that films prepared from TEO/β-CD microcapsules included in compression-molded wheat gluten matrices showed great potential to be used as an active food packaging.
