"In the United States, castoreum is considered to be a GRAS food additive by the Food and Drug Administration. It is often referenced simply as a "natural flavoring" in products' lists of ingredients. While it is mainly used in foods and beverages as part of a substitute vanilla flavour, it is less commonly used as a part of a raspberry or strawberry flavoring. The annual industry consumption is very low, around 300 pounds, whereas vanillin is over 2.6 million pounds annually."
