| Abstract: | This paper deals with a study on fatty acids of corn kernels in China.608 cornvarieties were collected from 20 provinces as the experimental materials.The fatty acidswere determined with a gas-chromatography.The statistical results showed that the av-erage contents of fatty acids were as follow:Linoleic acid(18:2):46.67%;Oleicacid(18:1):34.18%;Palmitic acid(16:0).15.02%;Stearic acid(18:0):2.25%;Linolenic acid(18:3):1.31%;Arachic acid(20:0):0.33%.The total content ofthe unsaturated fatty acid was 82.16%.A region classification based on the fatty acid content was done with cluster analy-sis method.A tendency was found that the contents of linoleic acid and.the totalunsaturated fatty acid were higher in the north part of China than those in the south,and the palmitic acid,oleic acid and the total saturated fatty acid were just con-versely. |
