i wonder what is the scientific explanation for adding salt when u boil eggs?

Question

i know this tips that, if you boil eggs, you just add salt to the water so that when later you want to peel the skin the white part of the egg wont stick to the skin, i wonder what is the scientific explanation for it?

Answer 1

In case small cracks do develop, you add salt to the cooking water. Because salt will help to speed up the denaturing of the egg white, causing less of it to feather into the water. Use at least a tablespoon of table salt per two quarts of water.

there ya go...
and PS ...salt causes water to boil at a higher temperature as well.

Answer 2

I dont think that there is scientific explanation for the salt to shell/skin connection. I do know that if you add salt to water it changes the boiling temp. You just need to add alot more salt then you would like, I think a 1/4 cup per every quart changes the temp by 1 degree.

Answer 3

It does nothing to do with the peeling of the egg. Salt water will boil faster, at a lower temperature. Older eggs will peel easier then fresh eggs.

Answer 4

Salt also helps the egg for breaking right out of the cold freg!

Answer 5

it's is called research or maybe common sense!! they just do that to make people fatter b/c they skin stays on the egg
