Microparticles coated with proteins in their natural state and in vitro gastrointestinal simulation

Abstract This study aimed to produce pectin and alginate microparticles by ionic gelation coated with different concentrations of bovine blood egg white protein in their natural state. The were characterized, physical resistance morphology evaluated, as well the released during vitro gastrointestinal simulation. highest adsorption (65.47%) was shown (10%), regardless type concentration used. Likewise, higher amounts adsorbed resulted increased, microparticle. Nevertheless, affected more polysaccharide, being resistant. Adsorbed proteins on surface showed solubility values simulation type. Bovine state can be used alternative coating materials for microparticles.
