| 摘 要： | 大豆高支链氨基酸混合物是水解大豆蛋白质添加少量个别氨基酸制成的氨基酸混合物。其必需氨基酸含量占混合物的68.9％,支链氨基酸含量占42.9％。 动物喂养实验显示,此种氨基酸混合物能促进幼年大鼠生长,维持血红蛋白、血清总蛋白和白蛋白的正常含量,蛋白质功效比值(PER)、真消化率(TD)、生物价值(BV)、净蛋白质利用率(NPU)依次为2.78、94.0％、85.0％和80.0％。这些值均显著高于酪蛋白、略高于大豆平衡氨基酸,表明此种氨基酸混合物没有因支链氨基酸含量高而发生氨基酸拮抗作用,具有较高的营养价值。

| Abstract: | The soybean high branched-chain amino acid mixture was composed of soybean protein hydrolyzed by special method with a few types additional amino acids in small amount. The mixture contained 68.9% of essential ami-no acids and 42.9% of branched-chain amino acids.The animal experiment showed that the mixture could promote the growth of young rats and maintain the normal levels of Hb, serum total protein and albumin. Its protein efficiency ratio (PER), true protein digestibility (TD), biological value (BV) and net protein utilization (NPU) were 2.78, 94.0%, 85.0 and 80.0% respectively. These values were significantly higher than that of casein. The results indicated that the soybean high branched-chain amio acid mixture did not produce amino acid antagonism caused by the high amount of branched-chain amino acids and had higher nutritional quality. |
