Abstract: The present invention relates to a continuous process for denaturation of proteins, which comprises the steps of: a) subjecting a protein solution to a high pressure homogenizer at a pressure of about 500 to about 5000 bar, at a recirculation ranging from 0 to about 50 and at a temperature ranging from about 20° C. to about 80° C. for a period of time on the order of milliseconds, wherein the protein solution consisting of a protein fraction dispersed in water, buffer or salt solution at a concentration ranging from about 2% to about 35% w/w and at a pH adjusted between about 2.0 to about 12.0; b) concentrating the protein solution by i) evaporation, ii) ultrafiltration and sprayed dried or iii) ultrafiltration and freeze dried.
