| 摘要: |
| 对甜荞 (Fagopyrum esculentum)和苦荞 (F.tartaricum)芽的蛋白质营养进行分析 ,并应用氨基酸比值系数法 ,对荞麦芽的氨基酸进行全面评价。结果表明 ,苦荞 (榆 6- 2 1 )芽的粗蛋白含量为 1 42 .91 g/kg,甜荞 (榆荞 1号 )芽的粗蛋白含量为 1 72 .72 g/kg。二者蛋白质中氨基酸种类齐全 ,必需氨基酸 (EAA)分别占总氨基酸的 43.1 9%和 40 .89%。第一限制性氨基酸为含硫氨基酸 (Met Cys)。甜荞芽菜的氨基酸比值系数分为 81 .97,略高于鸡蛋 ,苦荞芽菜的氨基酸比值系数分为 74.45,其蛋白质营养优于一般的蔬菜。抗营养因子检测未发现胰蛋白酶抑制剂活性。 |

| Abstract: |
| Using WHO/FAO reference model of essential amino acid (EAA) as an appraisal criterion,nutritional value of buckwheat seedling was evaluated with the method of ratio coefficient (RC) of amino acid.The results showed that the gross protein content was 14.291% in Yu 6 21 and 17.272% in Yuqiao No.1.The gross proteins were rich in all kinds of amino acid.EAA took up 43.19% and 40.89% of total amino acid,respectively.The first limiting amino acid was sulfur containing amino acid,met and cys.The score of RC (SRC) reached to 81.97 for the seedling of Yuqiao No.1,74.45 for the seedling of Yu 6-21.It is suggested that the seedling protein quality is far superior to that of other vegetables.Also there was no trypsin inhibitory activity in the seedling. |
