[edit] In food products
Acetoin, along with diacetyl, is one of the compounds that gives butter its characteristic taste. Because of this, manufacturers of partially hydrogenated oils typically add acetoin and diacetyl (along with beta carotene for the yellow color) to the final product, which would otherwise be tasteless.[1]
Acetoin is used as a food flavoring (in baked goods) and a fragrance. It can be found in apples, butter, yogurt, asparagus, black currants, blackberry, wheat, broccoli, brussel sprouts, cantaloupe.
[edit] Cigarette additive
In a 1994 report released by five top cigarette companies, acetoin was listed as one of the 599 additives to cigarettes. [2]
