Gas-Liquid partition chromatography and ultraviolet absorption of oils before and after hydrogenation

Summary Analyses of various natural fats and oils have been compared by G.L.P.C. and ultraviolet spectrophotometry. Good agreement was found for linoleic acid in unhydrogenated samples. The ultraviolet method gave lower results for linolenic acid. For hydrogenated oils the ultraviolet method gave lo...

520			\|a Summary Analyses of various natural fats and oils have been compared by G.L.P.C. and ultraviolet spectrophotometry. Good agreement was found for linoleic acid in unhydrogenated samples. The ultraviolet method gave lower results for linolenic acid. For hydrogenated oils the ultraviolet method gave lower results for both linoleic and linolenic acids in most instances where an appreciable amount of these components was present. It is known that the ultraviolet method measures only the naturally occurring isomers of the unsaturated fatty acids while the G.L.P.C. analysis includes all the isomers. This would account for the difference in responce between unhydrogenated and hydrogenated oils by the two methods of analysis.

abstract	Summary Analyses of various natural fats and oils have been compared by G.L.P.C. and ultraviolet spectrophotometry. Good agreement was found for linoleic acid in unhydrogenated samples. The ultraviolet method gave lower results for linolenic acid. For hydrogenated oils the ultraviolet method gave lower results for both linoleic and linolenic acids in most instances where an appreciable amount of these components was present. It is known that the ultraviolet method measures only the naturally occurring isomers of the unsaturated fatty acids while the G.L.P.C. analysis includes all the isomers. This would account for the difference in responce between unhydrogenated and hydrogenated oils by the two methods of analysis. © The American Oil Chemists' Society 1961
