| 摘 要： | 对2014年度南黄海绿潮藻进行分子鉴定和营养价值初步研究。ITS序列分析结果显示，南黄海绿潮藻主要包括Ulva linza procera prolifera（LPP）以及Ulva compressa 2个类群。营养价值分析结果显示，南黄海绿潮藻中必需氨基酸与氨基酸总量的比值（EAA/TAA）为30.31%～33.83%，呈味氨基酸含量较高（42.84%～46.89%），脂肪酸组成丰富，其不饱和脂肪酸中α 亚麻酸含量占总脂肪酸的（32.36±6.58）%，蛋白质含量与浙江固着浒苔相近（独立样本t检验，P>0.05），是一种高蛋白（26.46%～29.01%）、低脂肪（0.76%～0.91%）、富含纤维（4.87%～6.58%）且安全的海藻食品。

| Abstract: | Based on molecular identification，the nutritive value of green tide algae from the South Yellow Sea in 2014 was studied in this research. ITS sequence analysis showed that green tide algae in the South Yellow Sea were include in Ulva linza procera prolifera（LPP）and Ulva compressa. Nutritive value analysis indicated that green tide algae in the South Yellow Sea was a new safe and healthy sea food providing higher protein （26.46%-29.01%），lower fat（0.76%-0.91%） and higher dietary fiber （4.87%-6.58%）， whose protein content was similar with the attached algae from Zhejiang（independent t test，P>0.05）. The amino acid composition of protein was balance with 30.31%-33.83% for EAA/TAA，and the flavor amino acids contents were high （42.84%-46.89%）; meanwhile， the compositions of fatty acids in green tide algae from the South Yellow Sea were rich，the contents of alpha linolenic acid was (32.36±6.58)% of total fatty acids. The green tide algae was a safe seaweed food with high protein content (26.46%-29.01%), low fat content (0.76%-0.91%) and high fiber content (4.87%-6.58%). |
