“The eggs are the backbone of cooking, the cement that holds the castle of cuisine together.”
From the book mastering the art of southern cooking!
As you all know the main components of egg is albumen and yolk, which is mostly composed of protein. Apart from proteins egg white contains water, small amounts of minerals and sugars whereas the yolk contains fat, vitamins A, D and minerals such as calcium, thiamine, and riboflavin. Depending on the feed of the bird the yolk colour ranges from yellow to deep orange (when the birds are fed with good feed).
The proteins are made up of long chains of amino acids. In the raw eggs proteins are in their native state, i.e. they are in globular form, which means amino acids are twisted, folded and/or curled up in a very specific way giving the protein its shape and properties. Any induced alteration (mechanical or heat) to these proteins will in turn significantly alter the entire structure of the egg.
