## What Is Castoreum?
Beaver butt refers to castoreum, a scent-marking substance from beavers' castor sacs near their anus.

> The food industry can use virtually ANYTHING found in nature and label it as 'natural flavors'
## Why Did It Go Viral?
Vani Hari, known as 'The Food Babe,' popularized the term in 2022 to highlight FDA's use of 'natural flavors' for processed foods.

> These flavors work against you, getting you addicted to processed food using the best part of a taste or even a smell
## What Does It Taste Like?
Once processed and diluted, castoreum delivers warm, sweet notes that complement vanilla flavors.

> Castoreum gave flavor-makers another way to build that complexity, adding a musky, sometimes slightly smoky character
## Is It in Your Food?
Castoreum appears as 'natural flavor' in small amounts but is rarely used in food products.

> Castoreum is rarely used in food [but] is recognized as safe for its intended flavoring use
## Animal Welfare Concerns
Commercial castoreum often comes from beavers killed for fur, with castor sacs extracted using alcohol.

> Those sacs and their contents are dried, broken down, and extracted with hot alcohol to draw out the aromatic compounds
## Should You Worry?
No significant health risks exist, but animal welfare concerns remain for castoreum's sourcing.

> There's a legitimate animal-sourcing concern, even if the food-safety scare is overblown
## Key takeaway

Castoreum, a beaver secretion, is an FDA-approved natural flavor used in small amounts for taste, not a health risk.
