  • Patent number: 5019407
    Abstract: Disclosed is a method of pasteurizing a liquid whole egg product in a continuous stream. The method comprises the steps of: (a) providing an egg yolk product stream and an egg white product stream; (b) heating the egg yolk product stream to a predetermined temperature greater than the highest temperature of the egg white product stream; and then (c) recombining the egg yolk product stream and the egg white product stream to form a whole egg product stream, the whole egg product stream having (e.g., equilibrating to) a second predetermined temperature; wherein the total thermal treatment received by the liquid whole egg product during the process is at least sufficient to pasteurize the product.

  • Patent number: 4994291
    Abstract: Methods of ultrapasteurizing liquid whole egg products in continuous flow, high temperature, short time pasteurization equipment are provided. The equivalent point method is preferably used to evaluate the total thermal treatment received by the product in this equipment. Also disclosed is a method of making liquid whole egg products having preselected, extended, refrigerated shelf lives.

  • Patent number: 4957760
    Abstract: A method of continuously ultrapasteurizing liquid whole egg products is disclosed. The method provides improved run times and product viscosity control. In an embodiment of the method, the product is heated by contacting the product to a heated surface, heated by contacting the product to steam, held at the temperature to which it has been heated for a time sufficient to produce a nine log cycle reduction in Listeria monocytogenes therein, homogenized, cooled and aseptically packaged.
