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.
By William Leigh. The opaque, viscous orange centre of an egg, intended to feed the developing embryo. Egg yolks have a lower water content than the white that surrounds them, but contain higher levels of protein and significantly more fat. They have a much richer flavour, and are used to thicken sauces such as mayonnaise and custard. Contrary to popular myth, the colour of an egg yolk has no bearing on its quality â it simply reflects the breed of the hen, its diet and the time of year at which it was laid.
