You do this to add 'air' to the batter and make it fluffy crisp and light, first you must separate the egg yolk from the white, put the white into a clean grease free bowl and beat it with a whisk until it goes white and fluffy (takes ages by hand so use an electric whisk) then add this to the batter and fold it in, i.e. gently stir in the white into the batter so as not to knock out all the air you just whisked into it.
Whip egg whites and felty fold them into the batter
Some batters call for beaten egg whites to be added. Folding the whites in with a spatula keeps the air bubbles in them from breaking, which leads to a flat, heavy cake. Pour the whites into the batter, and using a spatula flat side up, gently distribute the whites from top to bottom of the bowl. Pour or spoon the batter gently into the pans to further avoid breaking the air bubbles.
You would use 4 medium egg whites or 5 small egg whites.

to give it fluffiness to the food item made
White? Do you mean egg whites for a meringue icing? If so, you can't substitute for egg whites unless you have purchased powdered egg whites. Do you mean white as a color and flavor? Any color/flavor will do, depending on your taste.
Yes there is protein in egg whites.
Why does an egg fold if you put it in vinegar?
if you mean like in a cake batter, it is simple. All you do is add small amount at a time to the batter and get a spoon and scrape from under neath over. so lets say adding egg whites to make a meringue, you would add a dollop of whites and get the spoon from the right side ( if right handed) under neath the mixture and bring up again folding the left side over. you do this ti add ingrediants but to keep air in. It is kinda hard to explain but i hope this helps! Good luck! :)
