Re: Can vinegar denature egg white and yolk?

You are absolutely right. Vinegar is used to denature proteins in foods in everyday cooking also, like in marinades or in making dishes like ceviche. But you can also denature proteins by mechanical methods, like making whipped cream or merangues, or traditional cooking. So the egg looked cooked because it was, just not by applying heat.

Here is another answer already posted that gives a great detailed explanation of what is happening in this egg experiment: Rubb er egg experiment

Thanks for asking!
