This study investigates the features of a new type of delivery system prepared by combining a natural outer eggshell membrane (OESM) with emulsified microcapsules. The loading efficiency, controlled release properties, and forming mechanisms of the prepared system were studied. The polysaccharide/protein microcapsules incorporated with vitamin E can be attached to highly cross-linked protein fiber networks of OESM. This attachment could be reinforced more than 2-fold using glutaraldehyde as a cross-linking agent. The combined OESM/microcapsule delivery system significantly exhibited better controlled release properties than the microcapsules alone because of the steric blocking effect. Moreover, the OESM delivery system incorporated with microcapsules formed by pectin/protein as wall material showed more resistance against enzymatic attacks because of the formation of compact aggregates promoted by electrostatic effects.
