avidin

A Dictionary of Food and Nutrition | 2005 | Copyright

avidin A protein in raw egg‐white which binds biotin, preventing its absorption. People who consume abnormally large amounts of uncooked egg (several dozen eggs per week) have been reported to show biotin deficiency. Avidin is denatured on cooking, and does not combine with biotin; indeed cooked egg is a rich source of available biotin.
