The procedure is accomplished by diluting and acidifying the yolk of eggs and heating the mixture to a pasteurizing temperature [heating for a sufficient period of time necessary for a 100,000-to-1 CFU/g (5D) reduction].
The first step is to recognize that if the egg yolk protein is mixed with an equal volume of water and from one-third to an equal volume of lemon juice or vinegar, the temperature at which coagulation of the egg yolk protein occurs is raised.
When the egg yolk/acid mixture is heated to 150F (65.6C), vegetative pathogenic bacteria are reduced at least 100,000 to 1 CFU/g, while the egg yolk proteins have not been heated sufficiently to denature and coagulate because of the water dilution and acid.
