  • Patent number: 5474794
    Abstract: A method for the rapid cooling of a raw egg in a shell, the shell egg being warm and having an internal temperature typically of about room temperature or higher. The method preferably involves placing the shell egg for about 1 to about 5 minutes in an atmosphere of cryogenic gas at a temperature of about -60.degree. F. (about -51.degree. C.) to about -120.degree. F. (about -84.degree. C.), whereby the internal temperature decreases sufficiently to inhibit residual pathogenic and/or spoilage microorganisms, such as Salmonella and/or Pseudomonas, respectively, present inside the shell egg. Also a cool raw shell egg in a shell that has been rapidly cooled in an atmosphere of cryogenic gas after having been warmed, typically to where the shell egg had an internal temperature typically of about room temperature or higher. The cool shell egg that has been so subjected to rapid cooling has fewer viable residual pathogenic and spoilage microorganisms, i.e.
