Beavers secrete a goo from their butts called castoreum. Castoreum has a vanilla scent and is sometimes used as an artificial flavoring in foods.
Castoreum is and has been used to help mimic the flavor of vanilla, raspberry, and strawberry flavors in foods such as ice cream, chewing gum, pudding, and much more for over 80 years. It has and is also used in perfume due to its scent.
With that said, it is not commonly used and is not used in large amounts because it is expensive.
What is Castoreum?
Castoreum is secreted from beavers’ castor glands found in both sexes of beavers. Castor is a pasty pungent brown goo with a strong scent used to market territory and keep predators away.
Oddly, castoreum supposedly smells good. So good, in fact, it is often used in foods.

How Common is Castoreum?
As noted above, castoreum is not commonly used in foods, mostly because it is expensive. It is not easily extracted from beavers (one either needs to “milk” the beaver or extract the gland). This makes other methods of creating artificial flavoring, for example, Vanillin, more popular in general.
To cite Wikipedia citing the beaver butt lover’s resource Fenaroli’s Handbook of Flavor, “The annual industry consumption [of castoreum] is very low, around 300 pounds, whereas vanillin is over 2.6 million pounds annually.”
