A popcorn-like smell has an unexpected source
Binturongs are associated with a popcorn-like odor. Their urine contains 2-acetyl-1-pyrroline, a compound also involved in popcorn’s aroma. The connection comes from chemistry rather than a popcorn snack. A familiar smell can turn up in an unfamiliar place.
The aroma has a source far from a cinema counter.
