Beaver butts secrete a goo called castoreum, which the animals use to mark their territory. The U.S. Food and Drug Administration lists castoreum as a “generally regarded as safe” additive, and manufacturers have been using it extensively in perfumes and foods for at least 80 years, according to a 2007 study in the International Journal of Toxicology.
Castoreum is a chemical compound that mostly comes from a beaver’s castor sacs, which are located between the pelvis and the base of the tail. Because of its close proximity to the anal glands, castoreum is often a combination of castor gland secretions, anal gland secretions, and urine.
Instead of smelling icky, castoreum has a musky, vanilla scent, which is why food scientists like to incorporate it in recipes.
My utmost apologies if you're having a desert/meal that consists of Vanilla flavoring let alone general food.
This claim disgusts me. Is it true?
