The beaver connection
Castoreum is a substance that beavers emit to identify their territory. Castoreum has a pleasant aroma because to the particular diet of beavers, and is often applied in vanilla flavoring. The chemical is not found in the beaver’s feces or urine. Castor sacs, which are placed near to the beaver’s anal glands, produce this yellowish oily fluid.
Castoreum was never the main ingredient in vanilla flavoring; it was only utilized to bring out some nice aromas.
Castoreum is a safe addition that can be used to manufacture extract or essence that is then used to make cakes, cookies, shakes, and ice creams, according to the US FDA. For the past 80 years, castoreum has been used to vanilla flavoring to manufacture fragrances, lotions, candles, and delicacies.
