Aliphatic Monoketones in Flavors

Michael Zviely, CIC

Ketones are responsible for many natural flavors and odors. Ketones exist in their precursor form in fresh butter as alkanoic acids. As acids, they may be only marginally important in contributing to the flavor of fresh butter. However, when heated, these acid precursors are converted to different ketones and their total concentration rises above their flavor threshold value. Thus, they are very important in providing flavors associated with heated or cooked foods containing butter. Aliphatic ketones are important flavor components, especially in blue cheeses; Penicillium roqueforti, for instance, produces 2-pentanone, 2-heptanone and 2-nonaone.
