Abstract:
A gas chromatographic method was established for the analysis of fatty acid composition of oils. After methlation of the samples, the retention time of the fatty acid esters in the glass capillary coated with crosslin-ked methyl silicone was closely related to the number of carbon atoms.The reproducibity of this method was satisfactory. The relative standard deviation was 0.4-1.5%. Six kinds of vegetable oils were analyzed by this method, and the results were consistent with those reported by Canadian Cereal Association. For analysis of the free fatty acid composition of becte-ria, the results were comparable with those obtained from thin layer chroma-tography and chemical analysis.
