Acetoin

1-Hydroxyethyl methyl ketone

C4H8O2 (88.0524)


Acetoin, also known as dimethylketol or 2,3-butanolone, belongs to the class of organic compounds known as acyloins. These are organic compounds containing an alpha hydroxy ketone. Acyloins are formally derived from reductive coupling of carboxylic acyl groups. Thus, acetoin is considered to be an oxygenated hydrocarbon lipid molecule. Acetoin is used as an external energy store by a number of fermentive bacteria. Acetoin, along with diacetyl, is one of the compounds giving butter its characteristic flavor. Acetoin is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Acetoin is used as a food flavoring (in baked goods) and a fragrance. Acetoin is a sweet, buttery, and creamy tasting compound. Outside of the human body, Acetoin has been detected, but not quantified in several different foods, such as cocoa and cocoa products, evergreen blackberries, orange bell peppers, tortilla chips, and pomes. This could make acetoin a potential biomarker for the consumption of these foods. Constituent of beer, wine, fresh or cooked apple, fresh or cooked leak, corn, honey, cocoa, butter, cheeses, roasted coffee and other foodstuffs. Acetoin, with regard to humans, has been found to be associated with several diseases such as eosinophilic esophagitis and ulcerative colitis; acetoin has also been linked to the inborn metabolic disorder celiac disease. Acetoin is a colorless or pale yellow to green yellow liquid with a pleasant, buttery odor. It can be found in apples, butter, yogurt, asparagus, black currants, blackberry, wheat, broccoli, brussels sprouts, cantaloupe. Constituent of beer, wine, fresh or cooked apple, fresh or cooked leak, corn, honey, cocoa, butter, cheeses, roasted coffee and other foodstuffs. Flavouring ingredient. [DFC]
