Several Fatty Acids in Edible Oils Measurement and Analysis

Using gas chromatography butter,soybean oil,sunflower oil,olive oil,walnut oil,almond oil fatty acid composition of the six oil were analyzed.The six major fatty acids in cooking oil are palmitic acid,stearic acid,oleic acid,linoleic acid,linolenic acid;in these five fatty acids,palmitic acid,stearic acid,oleic acid is the highest butter respectively 25.0 %,31.6 %,25.0 %,linoleic acid and linolenic acid content of soybean oil was the highest,69.3 %,respectively,and the content of 9.75 %,the oil content of unsaturated fatty acids were 62.084 %,93.057 %,84.485 %,95.524 %,97.323 %,97.962 %;the oil content of unsaturated fatty acids were higher,and thus has a high nutritional value.
