随着农业生产水平和人们生活水平的提高,农业科研人员对选育蛋白含量高的作物品种越来越注重。美国农业部最近取得一项新的研究成果,即用简单、廉价的方法分离出蛋白含量较高的小麦种子。这种分离方法的原理是:小麦种子的蛋白质与淀粉的比重不同。通过水浸后,种子中的蛋白质吸收水分要比淀粉多五倍。因此降低了高蛋白种子的比重,最后用溶液浮选法将高蛋白种子清选出来。具体做法是:先将小麦种子浸泡在水温稍微高于 With the improvement of agricultural production and people’s living standards, agricultural researchers pay more and more attention to crop varieties with high protein content. The United States Department of Agriculture recently made a new study that used simple, inexpensive methods to separate wheat seeds with high protein content. The principle of this separation method is: the proportion of wheat seed protein and starch are different. After flooding, the protein in the seed absorbs moisture five times more than starch. Thus reducing the proportion of high-protein seeds, the final solution flotation of high-protein seeds will be cleared. The specific approach is: first soaked wheat seeds in the water temperature slightly higher than
