Gas Chromatography of Fusel Oils in Alcoholic Distillates

Abstract

A single gas-liquid chromatographic column is described which will separate all the major fusel oil components rapidly and directly without prior concentration or extraction procedures. Quantitative data obtained using a 1:1 2% 1,2,6-hexanetrio 1:2% glycerol column compare favorably with those of the official AOAC colorimetric fusel oil method. Four additional components may be determined simultaneously and quantitatively.

Whiskey Composition: Identification of Additional Components by Gas Chromatography‐Mass Spectrometry

“…2 Identified as such, in tail fractions only; Ethyl lactate, peak 3, was identified in whiskey by several workers and also in this laboratory. (See Kahn et al, 1968b).…”

Refining of methods for subjective-objective evaluation of flavor

“…After it was seen that the panelists had no strong preference, identification studies were discontinued. About 80 compounds have been identified in whiskies of various types (Jones and Wills, 1966;deBecze et al, 1967;Kahn et al, 1968;Nykanen et al, 1968;Suomalainen and Nykanen, 1966;Schoeneman et al, 1971;Nishimura and Masuda, 1971;Jennings et al, 1972. The trials with the canned peaches were the most consistent on the organoleptic side. The panel clearly differentiated the various brands of peaches in all categories.…”

A Single Column Gas Chromatographic Method for the Direct Trace Analysis of High Boiling Components in Rums

“…Direct analytical packed column gas chromatographic analyses of components present in distilled alcoholic beverages, such as whisky, brandy, and rum, have been done almost since the advent of this unique technique (2,3). Although many high-efficiency packed columns are available for this purpose, when direct analysis of distilled alcoholic beverages is required, only a limited number of components may be determined in a single separation (1,4). This is because not more than 10 components are at sufficiently high concentration for adequate separation and quantitative measurement.…”
