[Determination of the ethyl esters of long chain fatty acids in wine distillate, brandy, and wine. II. (author's transl)].
Free fatty acids are able to interfere the determination of the ethyl esters by gas chromatography on Carbowax 20 M. Therefore series of tests were made to remove the fatty acids. Sodium hydrogen carbonate was found to be more suitable than sodium carbonate. A method is described to determine the ethyl esters of fatty acids of caproic to stearic acid and of the unsaturated fatty acids with 16 and 18 carbon atoms.
