摘　　要：为了开发和利用玉米皮资源,对玉米皮的营养成分以及玉米皮油的理化指标和脂肪酸组成及甘三酯组成进行了分析测定。结果表明,玉米皮粗脂肪含量为5.99%,粗蛋白质4.86%,粗纤维含量为12.45%;玉米皮油富含不饱和脂肪酸,含量高达80%以上,玉米皮油的理化指标为相对密度d2400.9135,碘值112.4 gI/100 g,皂化值189.1 mgKOH/g,不皂化物3.75%。In order to promote the development of corn bran source, the nutritional components of corn bran, physicochemical properties and fatty acid compositions of corn bran oil were analyzed. The results show that the crude fat in corn bran is 5.99%, the crude protein is 4.86%, the crude fiber is 12.45%. The content of unsaturated fatty acid is 84.41%,the physical and chemical index of com bran oil is as following： d420 0. 9135, IV 112.4 gI/100 g, SV 189.1 mgKOH/g, unsaponifiable matters 3.75 %.
