"Natural aromas can be extracts from plants, fungi, and in some cases animals." Ulla Beckman Sundh, an agency representative reported.
But she said the beaver will likely not become a common source of vanilla, as the supply is limited because the beaver is not bred.
Beavers were wiped out in Sweden in the 19th century, but the population has grown to 100,000 after the animal was imported, The Local.se said.
