ABSTRACT:
A process for the continuous pasteurization of eggs characterized in that liquid egg material is passed under a superatmospheric operating pressure through a first scraped surface heat exchanger to raise the temperature of the egg material to the pasteurization temperature after which it is passed to a heated holding vessel under pressure of a sterile inert gas for a period of time which ensures pasteurization but which is sufficiently short to ensure that substantially no coagulation occurs, and finally through a second scraped surface heat exchanger where it is cooled to a temperature below 10.degree. C. over a period of time less than 5 minutes.
