  • Patent number: 9949497
    Abstract: There is a process which can pasteurize in-shell chicken eggs to inactivate pathogens when present which includes all strains of salmonella and all strains of viruses that historically have been known to exist within chicken eggs and currently are known to be evolving into new and separate strains which may cause large quantities of human illnesses unless countermeasures are developed and employed. One such countermeasure is provided through pasteurization of the subject in-shell eggs through pasteurization involving concurrently a secured environment together with a protocol which enables total inactivation of the targeted pathogens whether bacterial or viral without risk of recontamination.
    Type: Grant
    Filed: March 8, 2017

  • Patent number: 6692784
    Abstract: There is provided a process for pasteurizing in shell chicken eggs (2) carried in stacks (1) by placing the eggs in a heated fluid bath (4) having a temperature of between about 128 to 145 degrees F., allowing the eggs to dwell in the heated fluid bath until there is a log reduction of at least 4.6 of any Salmonella bacteria within the eggs, removing the eggs from the heated liquid bath and into a gaseous atmosphere (26), and contacting the eggs with an antibacterial fluid (28) containing an antibacterial agent. Preferably, the eggs are thereafter contacted with a sealant such as wax. In the gaseous atmosphere the eggs further pasteurize to at least a 5 logs reduction of the bacteria by way of residual heat in the eggs. During cooling in the gaseous atmosphere, the eggs suck the antibacterial fluid into the eggs between the inside of the shells and the membranes and provide antibacterial barriers in the eggs.

  • Publication number: 20020041921
    Abstract: A method of extending the safe shelf life of shell eggs is taught. Eggs are pasteurized by heating eggs until a central portion of the yolks of the eggs is at a temperature between 128° F. to 138.5° F. That temperature is preferably maintained and controlled for times within parameter line A and parameter line B of FIG. 1 and sufficient that any Salmonella species present in the yolk is sufficiently reduced but insufficient that an albumen functionality of the egg measured in Haugh units is unacceptably affected. The pasteurized eggs are further processed to extend the shelf life of the eggs, and to substantially reduce re-contamination of the eggs. Eggs entering the pasteurization process are initially treated with an anti-bacterial agent. The bath itself is fortified with an anti-bacterial agent of food quality and periodically fortified. Processed eggs are treated with an anti-bacterial agent, and sealed. The sealant material provides a barrier substantially eliminating re-contamination.
