And they didn't just go for a standard 10-minute hard boiled egg. No, the researchers decided, just to make absolutely sure the whites were cooked, to boil the eggs for 20 minutes at 194 degrees Fahrenheit. Adding urea to the eggs untangled the knotted proteins by chemically breaking them into bits, returning the eggs to a liquid form. (Note: Urea is one of the main ingredients in pee, so these unboiled eggs are probably not delicious.) Then the researcher put the (now liquid) solution into a machine called a 'vortex fluid device.' The device pieces the broken proteins back together within minutes—a vast improvement over older methods of reconstituting proteins, which could take days.
