GLC analyses of 200 samples of commercial fats and oils were compared to the standard ranges specified by the FAO/WHO Codex Alimentarius Committee on Fats and Oils at its seventh session held in London, England on March 25, 1974. A single range of values for each fatty acid in 10 commercial fats and oils (arachis, cottonseed, lard and rendered pork fat, maize, mustard seed, Premier Jus and edible tallow, safflower seed, sesame seed, soybean, and sunflower seed) was agreed upon. To facilitate handling of the data, computer programmes were written to compare proportions of fatty acids in each of the 200 samples with the corresponding ranges given for each fat. Data from the computerized matching are summarized in tabular form. Only 6 samples fell outside the standard ranges. On the basis of this information the US delegation is offering for consideration by the Committee at its next meeting a method for using the fatty acid composition of a fat or oil to determine its authenticity.
