Constituents of Fusel Oils Obtained Through the Fermentation of Corn, Barley and Sweet Molasses

Abstract

The components of the fusel oils obtained through the fermentation of corn, barley and sweet molasses were separated by fractional distillation and adsorption chromatography. Each of the components was analyzed by gas chromatography and infrared spectrometry. Newly isolated components were as follows: methyl heptenone, fatty acids having odd number of carbon atoms, acetic esters of higher aliphatic alcohols ranging from C6 to C11, benzyl alcohol, ethyl phenylacetate, phenylethyl propionate, acetophenone, limonene, and α-ionone. Moreover, an unknown ketone C10H16O were isolated from corn fusel oil, and trans-neroridol from sweet molass fusel oil.
