Abstract
A method of pasteurizing in-shell chicken eggs by heating eggs until a central portion of the yolks of the eggs is at a temperature between 128.degree. F. to 138.5.degree. F. That temperature is 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 reduced by at least 5 logs but insufficient that an albumen functionality of the egg measured in Haugh units is substantially less than the albumen functionality of a corresponding unpasteurized in-shell egg.
Claims18
A method of pasteurizing an in-shell chicken egg, comprising heating the egg until a central portion of a yolk of the egg is controlled within a temperature range of 128.degree. F. to 138.5.degree. F. and maintaining that controlled yolk temperature range for times, (i) within parameter line A and parameter line B of FIG. 1 and (ii) sufficient that a Salmonella species present in the egg yolk is reduced in amount by at least 5 logs such that the egg is pasteurized but (iii) insufficient that an albumen functionality of the egg measured in Haugh units is substantially less than the albumen functionality of a corresponding unpasteurized in-shell chicken egg.
