1- One of the main parts of the egg is yolk: the yellow, inner liquid part of the egg where the embryo forms. It is the yellow part at the center of an egg. Yolk colour ranges from just a hint of yellow to a magnificent deep orange because it contains oil. The egg yolk is classified as a liquid despite of what many people think.

2- Nicolai Lunin showed that there was an unknown substance in milk that was essential for nutrition. It was also found in the egg yolk. Then Carl Socin suggested that an unknown substance for growth found in egg yolk was fat soluble. Although the idea of extracting oil from the egg yolk was far-fetched, luckily, it became a consummated reality.
