摘　　要：分析了黄官1号海带在大连和福建海域的一般营养成分、16种氨基酸及矿物质含量,并与大连北方早熟海带进行营养学对照评价。结果表明,地域的差异性对黄官1号海带营养成分的含量有重要的影响。其中主要的成分差异:福建黄官1号海带中粗蛋白、褐藻胶、总氨基酸、Fe、P、K、Na等的含量高于大连黄官1号海带,而甘露醇的含量则低于大连黄官1号。在氨基酸的组成分析中:福建黄官1号海带的氨基酸组成均衡,必需氨基酸(EAA)占氨基酸总量(TAA)的39.74%,必需氨基酸与非必需氨基酸的比值(EAA/NEAA)为0.66,均高于大连黄官1号海带的EAA/TAA比值与EAA/NEAA比值;但是在氨基酸的评分中,两者分数相差不大,均低于60分,受限氨基酸都为赖氨酸和蛋氨酸,因此黄官1号海带需要搭配其他的食物一起食用。The nutritional components, 16 kinds of amino acids and minerals of Saccharina Huangguan No.1 from Dalian and Fujian sea area were analyzed and compared with the control Saccharina cultivar. The results indicated that the difference of areas has great influence on the compositions of Huangguan No.1. The main differences for composition are that Fujian Huangguan No.1 contains more crude protein, alginate, TAA, Fe, P, K and Na than Dalian Huangguan No.1 does, while the mannitol in Fujian Huangguan No.1 was less than that in Dalian Huangguan No.1. The analysis of amino acid compositionshowed that Fujian Huangguan No.1 has proportionate amino acid composition with EAA/TAA of 39.74% and EAA/NEAA of 0.66. Both of EAA/TAA and EAA/NEAA of Fujian Huangguan No.1 were higher than that of Dalian Huangguan No.1. However, the amino acid score of Fujian and Dalian Huangguan No.1 were similar with each other and all lower than 60 points. The limited amino acids of Huangguan No.1 were Lysine and Methionine. So Huangguan No.1 should be eaten together with other food.
