Castoreum (or castor, not to be confused with the oil of a castor bean) is a yellowish-brown, unctuous substance with a strong, penetrating odor which beavers secrete from castor sacs located in skin cavities between the pelvis and the base of the tail. Because of its scent properties castoreum has long been employed in the perfume-making industry, and processed forms of castoreum have also been used as food additives, in the latter case primarily as enhancers of vanilla, strawberry and raspberry flavorings found in products such as iced tea, ice cream, gelatin, candy, fruit-flavored drinks, and yogurt.
