火麻籽及其油的理化性质研究

为了开发和利用火麻籽资源,以甘肃和宁夏火麻品种为原料,采用常规及仪器方法对火麻籽的主要营养成分、氨基酸组成及其油的脂肪酸组成和理化指标进行了分析测定.结果表明:甘肃和宁夏的火麻籽三维尺寸和物理特性比较接近,甘肃火麻籽的含油量大于宁夏的品种；两个品种火麻籽油的主要脂肪酸均为4种,不饱和脂肪酸的相对含量约为88％,其中α-亚麻酸相对含量均在20％以上；两个品种火麻籽的蛋白质含量相当,其氨基酸组成基本一致且比例合理；两个品种火麻籽的矿物质含量相当,但主要矿物质元素含量差别较大.火麻籽含有多种营养成分,具有较好的开发利用前景.

Physicochemical properties of hemp seed and its oils

In order to research and exploit hemp seed resource,the main nutritional ingredients and physicochmeical parameter of hemp seed and oil were analyzed by using the Gansu and Ningxia hemp seeds as raw materials.The results showed that the three dimensional size and physical properties of hemp seeds were not significantly different;the oil content of Gansu hemp seed was more than that of Ningxia’s,but the two oils contained 4 kinds of main fatty acid,and the unsaturated fatty acid content was about 88%,and the α-linolenic acid content was more than 20%;the protein contents of two hemp seeds were not significantly different,and they had quite similar amino acid composition and a good proportion;the mineral elements kinds of the two hemp seeds were not significantly different,but the main elements contents had significantly difference.There were rich nutritional ingredients in hemp seeds,which had wide prospect in food field.
