description. Egg yolk forms about 30% of an egg. It is the part of an egg which feeds the embryo, hence it is a major source of fat, protein, vitamin and minerals. Egg yolk mainly consists of protein and lipids, The lipid part is almost fully bound to proteins, as lipoproteins. This is why egg yolk is a good emulsifier.
On the left is the yolk of an egg produced by a free-range organic chicken, on the right is just the opposite â a store-bought, mass produced egg. Notice the difference in color. This is a common difference that will instantly give away âstore boughtâ eggs in the presence of natural, free-range organic eggs. The egg yolkâs color has implications regarding the nutrition and health of the chicken that produced it. A darker yolk is an indication of a nutritious and balanced diet rich in xanthophyll, omega-3 fatty acids and meats. Simply put, it takes quite a bit of time and energy to feed free-range chickens that produce eggs with a darker yolk.
