Castoreum
AvoidFlavoring Agent
Castoreum is a secretion from the castor sacs of beavers, historically used as a flavoring agent in foods and beverages.
What is Castoreum?
Castoreum is a natural secretion obtained from the castor sacs of beavers, located near the base of their tails. It has been historically used as a flavoring agent due to its vanilla-like aroma, although its use is now rare and often replaced by synthetic alternatives. Castoreum is sometimes used in natural flavorings and fragrances, though its occurrence in modern food products is minimal due to its animal origin and the availability of cheaper, synthetic vanillin.

Why People Avoid Castoreum
People, particularly those following a vegan diet, avoid castoreum because it is derived from animals, specifically beavers. Ethical concerns regarding animal welfare and the extraction process also contribute to its avoidance, along with the rarity of its use in modern food products.
