This could be a fantastic step in the progress toward treatment at a more reasonable price.

If you ever cooked an egg, you know that it’s made out of egg white and yolk. Egg whites are a low-calorie, fat-free food. They contain the bulk of the egg’s protein, while the yolks carry the cholesterol, the fat and saturated fat of the egg, but also important nutrients like essential fatty acids. When the whites are cooked, the proteins start to unfold under the thermal pressure, then fold again into a new tighter, more tangled structure – from clear and slimy, to white and gummy.


Researchers at the University of California, Irvine, and Flinders University in Australia now report a novel process that pulls apart these newly tangled proteins, allowing them to refold to their original structure. The team boiled eggs for 20 minutes at 194 degrees Fahrenheit then added urea to untangle the knotted proteins into liquid proteins known as lysozymes. Yes, urea is one of the main ingredients found in urine. I don’t know about you, but this unboiled egg doesn’t sound safe to eat again. The liquid was then processed in a machine called a vortex fluidic device, developed by Colin Raston and his colleagues at Flinders University in Australia, which causes the tangled protein molecules to shear and refold normally.
