Facilities, methods, and systems to produce therapeutic protein(s) can include collecting eggs from transgenic avian in a production unit in a building; transferring the eggs to a harvesting unit in the building; and harvesting egg white or egg yolk from the eggs in the harvesting unit.

Some embodiments are directed to a process for treatment of white liquid egg from chicken eggs or similar, including the steps of shelling the eggs so as to get a specific quantity of white liquid egg; filtering and immediately cooling the white liquid egg at a temperature in a range determined keeping the liquid inside a closed and agitated tank; heat treating by pasteurization the white liquid egg within a determined time interval by the shelling step with deaeration of the liquid and with addition of carbon dioxide; and performing a biochemical treatment of the white liquid egg in conditions of controlled temperature within a sterile tank with subsequent final storage at room temperature.

The present invention addresses the problem of providing an albumen hydrolysate that has emulsifiability, emulsion stability and heat coagulability. An albumen hydrolysate obtained by hydrolysis of albumen with a protease, wherein the dry weight of a precipitate formed by adding nine times the amount of 0.4 M trichloroacetic acid (TCA) to the albumen hydrolysate is 60% or more relative to the dry weight of albumen treated in the same manner.
