In more advanced contexts, "albumen" can also refer to a similar protein that is found in many animal tissues and fluids, not just in eggs. For instance, it can be discussed in biology or medical science when talking about proteins in the body.
While there are no common idioms or phrasal verbs that include the word "albumen," it may sometimes come up in phrases related to cooking or baking, such as "whip the albumen" or "separate the albumen from the yolk."
In summary, "albumen" is the white part of an egg, mainly made of water and protein. It is primarily used in cooking and food science, but it can also refer to a type of protein found in many living organisms.
