COMPOSITIONS CONTAINING ANTIBODIES TO FEL D1 AND METHODS FOR REDUCING AT LEAST ONE SYMPTOM OF HUMAN ALLERGY TO CATS Russian patent published in 2022 - IPC A61K9/14 A61K39/395 A61K47/36 A61K47/42 A61P37/08 

FIELD: chemistry and allergology.

SUBSTANCE: inventions group relates to the field of chemistry and allergology. 1 object is a food powder providing delayed release of anti-Fel D1 IgY antibody, which is a dried hydrogel containing gelatin, carrageenan and encapsulated anti-Fel D1 IgY antibody. 2 object - a method for obtaining a food powder, including the transformation of drops of a heated solution containing gelatin, carrageenan and IgY antibody to Fel D1 into a gel by placing the drops in a gel-forming bath containing salt or oil, with the formation of gelled granules, in which the IgY antibody to Fel D1 is encapsulated, and drying of the gelled granules. Object 3 - a method for producing food powder, including extrusion of a heated solution for cooling and shaping the heated solution and forming an extruded hydrogel, in which the IgY antibody to Fel D1 is encapsulated, and drying the extruded hydrogel. Object 4 - a method for obtaining a food powder, including spray drying a solution containing an IgY antibody to Fel D1 and 5.0-20.0 wt.% gelatin having a molecular weight of 2000 to 1 million daltons and/or a jelly strength value according to Bloom from 40 to 300, with the formation of a dried hydrogel, in which the IgY antibody to Fel D1 is encapsulated.

EFFECT: providing a controlled release of the anti-Fel D1 IgY antibody in the oral cavity of the cat, where the antibody binds to Fel D1.
