Panoramica

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.Acetoin is the main extracellular product of Bacilus subtilis grown on glucose and other fermentable carbon sources.It contributes to the aroma and flavor associated with alcoholic beverages. Production of acetoin by wine yeast fermentation has been reported.Acetoin is naturally present in buttery foods such as beer, butter and cheese.Determination of diacetyl and acetoin to evaluate the workplace exposures at a popcorn processing facility has been reported. Acetoin is an acyloin derivative. In the presence of light and moisture it transforms into a white colored solid dimer. It is formed by the reduction of diacetyl.It has been synthesized from acetaldehyde.
