Abstract

In order to guide the public to purchase healthy and nutritious edible oils, 14 kinds of market edible oils were selected and gas chromatography used to determine the fatty acids. The results showed that, with the exception of tea oil, olive oil 3 and flaxseed oil, the relative content of fatty acids in the other five kinds of oils was greater than 99.50%, with an average value of 99.12%. Most of the fatty acids have been measured. The results showed that the relative content of saturated fatty acids in 14 kinds of edible oils was between 9.45%~21.33%, with an average value of 15.69%; the relative content of unsaturated fatty acids was between 75.69%~88.91%, with an average value of 83.43%, of which the average value of monounsaturated fatty acids was 53.51%, and the average value of polyunsaturated fatty acids was 29.92%. The oil with the highest total content of saturated fatty acids was peanut oil 1, and the lowest was flaxseed oil. The oil with the highest oleic acid content in the unsaturated fatty acids was camellia oil, and that with the highest linoleic acid and linolenic acid content was flaxseed oil, and the oil with highest peanut-tetraenoic acid was tea oil
