种子蛋白质对于人及家畜来说是重要的蛋白质来源。其营养价值以动物蛋白质的氨基酸做为100%,种子蛋白质则为40～75%。然而,在麦类中的赖氨酸,豆类中含硫氨基酸则成为第一的必需氨基酸。又,蛋白质含量的平均干物重豆类为20～40%,而谷物类较低,一般为7～14%,因此,提高做为营养源并占有重要位置的植物种子蛋白质的品质,应首先做好氨基酸的平衡,其次有必要增加蛋白质的含量。另一方面,伴随气候异常,土壤贫弱等作物栽培环境的恶化,人口激增,食粮不足等全球问题,今后含有优质蛋白质的种子作物的生产是一个非常重要的研究课题。
Seed protein is an important protein source for humans and livestock. Its nutritional value to animal protein amino acid as 100%, while the seed protein is 40 to 75%. However, lysine in legumes and sulfur-containing amino acids in legumes are the first essential amino acids. In addition, the average protein content of dry matter weight of beans is 20 to 40%, while the cereal is low, usually 7 to 14%, therefore, to improve as a nutrient source and occupies an important position of plant seed protein quality, should first do Good amino acid balance, followed by the need to increase the protein content. On the other hand, with the global problems of crop cultivation environment such as climatic anomaly and soil weakness, population explosion and insufficient food supply, the future production of seed crops containing high-quality protein is a very important research topic.
