Alpha-Diketones

Other Alpha-Diketones

Other flavoring chemicals include 2,3-hexanedione and 2,3-heptanedione, which are also alpha-diketones. Although their toxicity has not been studied, it is possible that they may cause comparable damage to the smallest airways of the lung as diacetyl and 2,3-pentanedione.
