Vanillin

Vanillin is the molecule that makes vanilla taste like vanilla, and most of it is made in a factory or from wood. Despite the internet's favourite rumour, it is not beaver.

Where it hides

  • Vanilla-flavoured foods and drinks
  • Baked goods and chocolate
  • Ice cream and desserts
  • Pharmaceuticals

What it is

Vanillin is the compound responsible for vanilla's flavour. A little comes from real vanilla pods, but most is made far more cheaply:

Synthetic vanillin is now used more often than natural vanilla extract as a flavoring in foods, beverages, and pharmaceuticals.

Not the beaver myth

Synthetic vanillin is made from petrochemicals or from lignin, a by-product of wood pulp, and natural vanillin comes from vanilla beans. All of these are vegan. The persistent rumour that vanilla flavour is castoreum, a beaver secretion, is wrong: castoreum is expensive and vanishingly rare in food, while vanillin is cheap and everywhere.

Frequently asked

Is synthetic vanilla vegan?

Yes. Synthetic vanillin is made from petrochemicals or wood-derived lignin, and natural vanillin comes from vanilla beans. Both are vegan.

Is vanilla flavour made from beaver?

No. That refers to castoreum, which is expensive and almost never used in food. Vanilla flavour is vanillin, from plants or synthesis, and is vegan.
