摘要: 采用氨基酸自动分析仪对海蓬子不同部位氨基酸组成进行分析和比较,并对其营养价值进行评价。结果表明:海蓬子嫩茎、茎秆、根部位中均含有16种氨基酸,其中必需氨基酸8种,比例比较均衡。海蓬子嫩茎部位蛋白质含量最高,达到16.53%,必需氨基酸含量58.04mg/g、必需氨基酸与非必需氨基酸比值0.59、氨基酸比值系数分65.72,符合WHO/FAO的推荐标准。研究表明,海蓬子嫩茎有较高的营养价值和良好的开发利用前景。Abstract: The amino acid profiles of different parts of Salicornia bigelovii were determined using amino acid analyzer. The results showed that 16 common amino acids and 8 essential amino acids were found in the tender stems, stalks, and roots of Salicornia bigelovii in a balanced ratio, respectively. The protein content of tender stems was 16.53%, which was higher than other parts of Salicornia bigelovii. The essential amino acid content was 58.04mg/g, the ratio of essential amino acid content to non-essential amino acid was 0.59, and the SRC was 65.72, which were according with those recommended by FAO/WHO. The study showed that tender stems of Salicornia bigelovii had higher nutritional value with good prospects for the development and utilization.
