This topic has been shot to Swiss cheese and as the saying goes, beating a dead horse still gives the it some illusion of life. Don't confuse liquid eggwhites with raw eggwhites, the stuff from a fresh egg is raw, the stuff in a carton has been pasteurized.
I got interested in drinking liquid egg whites again because I'm tired to scrubbing egg pans, its also simple and hassle free. I boil my eggs now but I can run through maybe 2-3 dozen eggs in a week. I'm now considering spraying pam on an egg poacher and boiling eggwhites.
I can't seem to find the pasteurization temperature on the UEP certified website for the cartons of egg whites that can be picked up from the local HEB store. I can't seem to find the temperature on the Papetti website either, and now I don't really trust either of them due to the shear lack of information on their liquid egg whites. The carton does have pasteurized on it but that doesn't say much, other than some kind of heat treatment was done.
Other egg whites are pasteurized at about 134F to kill off the bacteria and I read that throwing it in the microwave for about ten seconds will probably do it some good. I got to searching about what temperature the denatureization of the protein happens at and it seems to start at, more or less, 50C, or, 122F. The pasteurization is done at 134F for eggwhites that actually tell you what temperature its done at.
http://bigbro.biophys.cornell.edu/~toombes/Science_Education/Gels_Polymers/Temperature_Acid_Egg_Unfolding.htm http://www.chemistryexplained.com/Co-Di/Denaturation.html Liquid eggwhites should not smell at all and if they do then they have been infected with something and need to be thrown out, kind of like sour milk.
Simply put: If denaturization of egg protein occurs at (50C/122F), and the pasteurization is done at (56.6C/134F), wouldn't that mean that liquid eggwhites from a carton can be safly added to a shake with a large amount of the protein content being availible for use?
Should I just go buy a big poacher?
Note: Unless you have had your ass turned raw and the near inability to walk from eating raw mustang grapes, don't whine about getting some bad eggs. Them grapes make you shoot something so acidic that it could probably be a new rocket fuel for NASA. :P

I guess I may have to find out for myself and try it...

Don't try it.
