Albumin vs. Albumen — What's the Difference?
By Tayyaba Rehman & Fiza Rafique — Updated on March 26, 2024
Albumin refers to a type of protein found in blood plasma and other bodily fluids, important for maintaining osmotic pressure, while albumen is the white part of an egg, rich in protein and water, used in cooking and as a binding agent.

Key Differences
Albumin is a family of globular proteins, soluble in water and moderately concentrated salt solutions, playing a vital role in regulating blood volume and as a carrier for molecules. It is essential in medical diagnostics as an indicator of health. Conversely, albumen, specifically the egg white, is utilized extensively in culinary arts, not just for its nutritional value but also for its ability to bind ingredients, leaven, and emulsify sauces.
While both albumin and albumen are proteins, their functions diverge significantly. Albumin's function in the body includes transporting substances, maintaining osmotic pressure, and supporting growth and repair. Albumen's role in cooking involves improving texture, providing moisture, and acting as a foaming agent in dishes like meringues and angel food cakes.
In medical contexts, albumin levels in the blood are a critical health marker, indicating liver function, nutritional status, and the presence of diseases. Albumen, on the other hand, is a subject of interest in food science for its properties like foaming, coagulation, and its ability to form gels, which are pivotal in food preparation and innovation.
The production and source of these proteins also differ. Albumin is naturally produced by the liver and is a reflection of both dietary intake and the body's health. Albumen, while also naturally occurring, is derived from egg whites and is a key ingredient in both traditional and modern culinary practices.
Despite the similarity in their names and their both being proteins, the distinction between albumin and albumen lies not just in their physiological and culinary roles but also in their scientific and nutritional significance. Albumin's importance in healthcare contrasts with albumen's versatility in the culinary world, illustrating the diverse functionalities of proteins.

Albumin
Albumin is a family of globular proteins, the most common of which are the serum albumins. All the proteins of the albumin family are water-soluble, moderately soluble in concentrated salt solutions, and experience heat denaturation.
Albumen
Same as Albumin.
Albumin
A simple form of protein that is soluble in water and coagulable by heat, such as that found in egg white, milk, and (in particular) blood serum

Albumen
The white of an egg, which consists mainly of albumin dissolved in water.
Albumin
Any of a class of water-soluble proteins that are found in egg white, blood serum, milk, and many other animal and plant tissues. Also called albumen.
Albumen

Albumin
(protein) Any of a class of monomeric proteins that are soluble in water, and are coagulated by heat; they occur in egg white, milk etc; they function as carrier protein for steroids, fatty acids, and thyroid hormones and play a role in stabilizing extracellular fluid volume.
Albumen
The white part of an egg; being mostly the protein albumin and water.
Albumin
A thick, viscous nitrogenous substance, which is the chief and characteristic constituent of white of eggs and of the serum of blood, and is found in other animal substances, both fluid and solid, also in many plants. It is soluble in water and is coagulated by heat and by certain chemical reagents.

Common Curiosities
Why is albumin important in medical diagnostics?
It indicates liver function, nutritional status, and can signal health issues.
Can albumin and albumen be used interchangeably?
No, they serve different functions; albumin is related to health and albumen to culinary uses.
How does albumen contribute to cooking?
It binds ingredients, helps in leavening, and can emulsify or foam, enhancing texture and consistency.
Are there dietary sources of albumin?
Albumin is produced by the body and is not directly obtained from the diet; dietary proteins can support its production.
How are albumin levels tested?
Through blood tests that measure its concentration in the blood plasma.
What distinguishes albumin from albumen?
Albumin is a blood protein essential for health, while albumen refers to egg white, used in cooking.
What happens to albumen when it's heated?
It coagulates, turning from liquid to a solid form, which is useful in culinary preparations.
Does albumin have a role outside of health?
Primarily, its significance is in health and medical fields, though it's also studied in biochemical research.
How do albumin and albumen impact food science?
Albumen is significant in food science for its functional properties, while albumin's relevance is more in nutritional studies.
Can albumin levels fluctuate?
Yes, they can vary due to health conditions, nutritional status, and hydration levels.
Are there synthetic forms of albumin or albumen?
Synthetic albumin exists for medical uses, while albumen's substitutes in cooking come from various plant-based sources.
