eggs
Eggs are laid by female animals of many different species, including birds, reptiles, amphibians, and fish, and have been eaten by humans for thousands of years.[1] Bird and reptile eggs consist of a protective eggshell, albumen (egg white), and vitellus (egg yolk), contained within various thin membranes. Popular choices for egg consumption are chicken, duck, quail, roe, and caviar, but the egg most often consumed by humans is the chicken egg.
Bird eggs have been valuable foodstuffs since prehistory, in both hunting societies and more recent cultures where birds were domesticated. The chicken was probably domesticated for its eggs from jungle fowl native to tropical and subtropical Southeast Asia and India before 7500 BCE. Chickens were brought to Sumer and Egypt by 1500 BCE, and arrived in Greece around 800 BCE, where the quail had been the primary source of eggs.[5] In Thebes, Egypt, the tomb of Haremhab, built about 1420 BCE, shows a depiction of a man carrying bowls of ostrich eggs and other large eggs, presumably those of the pelican, as offerings.[6] In ancient Rome, eggs were preserved using a number of methods, and meals often started with an egg course.[6] The Romans crushed the shells in their plates to prevent evil spirits from hiding there.[7] In the Middle Ages, eggs were forbidden during Lent because of their richness.[7] The word mayonnaise possibly was derived from moyeu, the medieval French word for the yolk, meaning center or hub.[7]
Egg scrambled with acidic fruit juices were popular in France in the 17th century; this may have been the origin of lemon curd.[8]
The dried egg industry developed in the 19th century, before the rise of the frozen egg industry.[9] In 1878, a company in St. Louis, Missouri started to transform egg yolk and white into a light-brown, meal-like substance by using a drying process.[9] The production of dried eggs significantly expanded during World War II, for use by the United States Armed Forces and its
