Description

A naturally occurring, water-soluble protein found in Egg white , Milk, and Blood. When spelled as Albumen, the use generally refers to egg white proteins used in the food industry and in 19th century photographic emulsions. Albumin is a strong, coagulating protein that is used in adhesives, paper coatings, lithographic, and photographic emulsions, textile dyeing, gilding leather, paint binders, and varnishes. Dried albumin powder is yellowish and forms a colorless solution in water. Albumin protein will remain water soluble used unless heated to temperatures above 50C (122F) or exposed to intense or long-term light. Medicinally, it is used as an antidote for mercury poisoning.

See also Casein.
