This thesis deals with the synthesis of protein and composite protein-mineral microcapsules by the application of high-intensity ultrasound at the oil-water interface. While one system is stabilized by BSA molecules, the other system is stabilized by different nanoparticles modified with BSA. A comprehensive study of all synthesis stages as well as of resulting capsules were carried out and a plausible explanation of the capsule formation mechanism was proposed. During the formation of BSA microcapsules, the protein molecules adsorb firstly at the O/W interface and unfold there forming an interfacial network stabilized by hydrophobic interactions and hydrogen bonds between neighboring molecules. Simultaneously, the ultrasonic treatment causes the cross-linking of the BSA molecules via the formation of intermolecular disulfide bonds. In this thesis, the experimental evidences of ultrasonically induced cross-linking of the BSA in the shells of protein-based microcapsules are demonstrated. Therefore, the concept proposed many years ago ...
