“…Nowadays, protein-based biologically active compounds and drugs, such as hormones, antioxidants, enzymes, enzyme inhibitors, vaccines, antitumor agents, etc., have gained wide application in medicine, food industry, and biotechnology. On the other hand, their use is associated with some limitations, the main of which are related to high sensitivity of proteins and medicines to denaturation, aggregation, or hydrolysis in the gastrointestinal tract (GIT), undesirable interactions of components of a medicine with each other or with other medicines, poor absorption of proteins in the GIT, hydrophobicity, instability and degradation on storage, toxicity, and immunogenicity of foreign protein components [1][2][3][4][5]. One of the approaches to overcome these limitations is based on encapsulation of proteins using appropriate carriers [1,[6][7][8][9][10][11].…”
