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, brussels sprouts, cantaloupe.he conversion of acetoin into acetyl-CoA is catalysed by the acetoin dehydrogenase complex, following a mechanism largely analogous to the pyruvate dehydrogenase complex; however, as acetoin is not a 2-oxoacid, it does not undergo decarboxylation by the E1 enzyme; instead, a molecule of acetaldehyde is released.
Acetoin is a volatile compound widely employed as flavour and fragrance compound in foods, cigarettes, cosmetics, detergents, chemical synthesis, plant growth promoters and biological pest controls. 2 Acetoin is the main extracellular product of Bacilus subtilis grown on glucose and other fermentable carbon sources.cetoin is suitable reagent used in 2,3 butanediol and acetoin production using Paenibacillus polymyxa (safe microorganism).
