对美国籽粒苋进行的营养品质和蛋白组分研究表明,它具有优良的营养品质。其籽粒、成熟期叶片和幼苗整株中蛋白质含量分别为干重的16%,18%及25%左右,氨基酸组成较为平衡。籽粒中赖氨酸含量为玉米的3.5—4倍,为小麦的2—3倍。籽粒中还含有较高的脂肪(6.5%左右)及亚油酸(48%左右)。碱溶谷蛋白约占种子蛋白总量的70%。除含硫氨基酸及苏氨酸以外,藏溶谷蛋白含有种子蛋白中50%以上的必需氨基酸。 Studies on the nutritional quality and protein components of American amaranth show that it has excellent nutritional quality. The protein content of the whole grain, mature leaves and seedlings were 16%, 18% and 25% of the dry weight respectively, and the amino acid composition was more balanced. The lysine content of the grain is 3.5-4 times that of corn and 2-3 times that of wheat. The grain also contains higher fat (about 6.5%) and linoleic acid (about 48%). Alkalinity accounts for about 70% of the total seed protein. In addition to sulfur-containing amino acids and threonines, heliotropin contains more than 50% of the essential amino acids in the seed protein.
