摘　　要：研究结果表明,太原种植的美国粒用苋品种,蛋白质含量在17.00～19.6％之间,平均为18.02±1.054％,变异系数5.8％。18种氨基酸总量5885.62mg/gN,必需氨基酸含量占37.9％,其中谷氨酸含量最高,占总量的18.4％。脂肪平均含量7.0±0.74％,必需脂肪酸的亚油酸占不饱和脂肪酸的81.3％。计算氨基酸分、化学分、氨基酸指数,并与食用粮、油相比,明确营养价值。Results of the study indicated that for the American grain amaranth grown in Taiyuan area, protein content ranged between17.00-19.6% with an average of 18.02+ 1.054% . Its variation coefficent was 5.8%.The total amount of 18 amino acids was 5885.62mg/gN. The tolal content of the essential amino acids is 37.9%, in which glutamic acid, being the highest in content, consisted 18.4% of the total amount. The average fat content was 7.0 + 0.74%. Linoleic acid accounted for 81.3% of the unsaturated fatty acid. Amino acid scores, chemical scores and essential amino acid indexes were calculated for amaranth and compared with those in food grain and edible oil, so as to ascertain the nutritive value of grain amaranth.
