摘　　要：为探究不同深远海养殖平台养殖大黄鱼品质差异,以深远海养殖平台“定海湾2号”(DH-2)和“闽投1号”(MT-1)养殖的大黄鱼为对象,采用国标生化分析方法对大黄鱼肌肉的常规营养成分、氨基酸和脂肪酸进行测定分析。结果表明:两组深海养殖平台的大黄鱼肌肉在常规营养成分、氨基酸和脂肪酸组成上较为一致,但在含量上存在着差异。除粗脂肪外,其余成分含量均表现为DH-2组高于MT-1组。两组大黄鱼肌肉中共检测到16种氨基酸,24种脂肪酸;其中氨基酸组成中以谷氨酸含量最高,脂肪酸组成中以棕榈酸(C16∶0)和油酸(C18∶1)含量最高。DHA和EPA含量DH-2组高于MT-1组。根据AAS和CS的评价标准,DH-2组和MT-1组第一限制性氨基酸均为缬氨酸;必需氨基酸指数(EAAI)分别为89.55和94.13,根据以上结果与FAO/WHO提倡的相关评价指标,在营养、口感味道等方面,DH-2组相对较优。这可为后续深远海养殖大黄鱼品质提升和高质加工提供技术参考。In order to explore the quality differences of Larimichthys crocea cultured in different far-reaching deepsea aquaculture platforms,the Larimichthys crocea cultured in the deep-sea aquaculture platforms"Dinghaiwan No.2"(DH-2)and"Mintou No.1"(MT-1)were used as the objects.The conventional nutrients,amino acids and fatty acids in the muscle of Larimichthys crocea were determined and analyzed by national standard biochemical analysis method.The results showed that the muscle of Larimichthys crocea in the two groups of deep-sea aquaculture platforms was more consistent in the composition of conventional nutrients,amino acids and fatty acids,but there were obvious differences in content.Except for crude fat,the contents of other components in DH-2 group were higher than those in MT-1 group.A total of 16 kinds of amino acids and 24 kinds of fatty acids were detected in the two groups of Larimichthys crocea muscle.Among them,the content of glutamic acid was the highest in the amino acid composition,and the content of palmitic acid(C16∶0)and oleic acid(C18∶1)was the highest in the fatty acid composition.The contents of DHA and EPA in DH-2 group were higher than those in MT-1 group.According to the evaluation criteria of AAS and CS,the first limiting amino acid for both DH-2 group and MT-1 group was valine.The essential amino acid index(EAAI)were 89.55 and 94.13,respectively.Based on the above results and the relevant evaluation indicators advocated by FAO/WHO,the DH-2 group was relatively better in terms of nutrition,taste and other aspects.This could provide technical reference for the quality improvement and high-quality processing of Larimichthys crocea in deep sea aquaculture in the future.
