Many commercial food products such as desserts, shakes and beverages are made with pasteurized liquid egg products; readyto- eat foods such as ice cream, eggnog, cookie dough, smoothies, mayonnaise, and Hollandaise sauce that contain these products are not subjected to further lethal treatment steps and so the egg ingredients must be Salmonella free.
Pasteurization of liquid egg whites must take place at lower temperatures than other liquid egg products so that the albumin does not coagulate.
Undiluted egg white will begin to coagulate at 60 C while egg yolk does not coagulate until it reaches approximately 70 C.
