Chemical Information
FooDB Name2,3-Pentanedione
Description2,3-Pentanedione, also known as acetyl propionyl, belongs to the class of organic compounds known as alpha-diketones. These are organic compounds containing two ketone groups on two adjacent carbon atoms. 2,3-Pentanedione is a sweet, butter, and caramel tasting compound. 2,3-Pentanedione is found, on average, in the highest concentration within beer. 2,3-Pentanedione has also been detected, but not quantified in, several different foods, such as green beans (Phaseolus vulgaris), blackberries (Rubus), fruits, milk and milk products, and breakfast cereal. This could make 2,3-pentanedione a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 2,3-Pentanedione.
