A recently filed patent (Publication Number: US20240034760A1) discloses a novel recombinant protein with specific structures involving milk proteins and linker peptides. The protein can have various configurations, including combinations of milk proteins with or without free thiol groups, linked via peptide bonds. The patent also details a method for producing casein using a recombinant host cell capable of producing the described recombinant protein structure. The method involves fermenting the host cell and includes specific criteria such as the presence of ß-lactoglobulin and casein, as well as linker peptides with recognition or cleavage sequences for a protease. The casein produced can be k-casein, b-casein, a-S1-casein, or a-S2-casein, and the protease used can be selected from various enzymes like chymosin, trypsin, and pepsin.

Furthermore, the patent also covers compositions containing the recombinant protein, which can be utilized in various products such as food, cosmetics, personal care items, films, coatings, sprays, gels, encapsulates, microspheres, nanoparticles, nanofibrils, nanotubes, foams, and biological scaffolds. These compositions can be used as food products, including dairy substitutes, animal meat substitutes, and egg substitutes, as well as in cosmetic and personal care products. The versatility of the recombinant protein opens up possibilities for a wide range of applications in different industries, highlighting its potential for innovation and product development.
