摘要:

为了解鸭绿江上游和下游斑鳜(Siniperca scherzeri)肌肉营养品质的差异, 本文对其肌肉常规营养成分含量、脂肪酸组成与含量进行测定和比较分析。结果显示:鸭绿江上游斑鳜粗脂肪含量显著高于下游斑鳜(P<0.05),两者肌肉中的水分、粗蛋白、灰分含量差异不显著(P>0.05);鸭绿江上游和下游斑鳜肌肉中分别含有16种和17种脂肪酸,上游斑鳜肌肉中饱和脂肪酸占35.886%、单不饱和脂肪酸占34.184%、多不饱和脂肪酸占29.922%,下游斑鳜肌肉中饱和脂肪酸占34.913%、单不饱和脂肪酸占34.895%、多不饱和脂肪酸占30.181%;从脂肪酸的组成特征来看,上游斑鳜肌肉中必需脂肪酸占11.735%、ω-6/ω-3比值为0.919、DHA+EPA含量占11.672%,下游斑鳜肌肉中必需脂肪酸占9.571%、ω-6/ω-3比值为0.781、DHA+EPA含量占12.939%。结果表明,鸭绿江斑鳜肌肉必需脂肪酸组成相对平衡,且含量较为丰富。以必需脂肪酸、ω-3系列多不饱和脂肪酸和ω-6系列多不饱和脂肪酸作为评价指标,上游斑鳜肌肉脂肪酸营养价值较下游斑鳜高。

Abstract:

To figure out the different nutritional quality of S.scherzeri muscle from different habitats, this study determined and compared the nutritional compositions, as well as fatty acids composition and content of S.scherzeri. The results showed that there was significantly higher crude fat content in the muscle of S.scherzeri in upstream area than that in the muscle of S.scherzeri in downstream area (P<0.05), without significance in content of moisture, crude protein and ash between these two groups (P>0.05). There are 16 kinds of fatty acids in the muscle of S.scherzeri in upstream area and 17 in downstream area. The saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids occupied 35.886%, 34.184% and 29.922% in the muscle of S.scherzeri in upstream area, occupied 34.913%, 34.895% and 30.181% in the muscle of S.scherzeri in downstream area, respectively. And for the composition of fatty acid, the essential fatty acid occupied 11.735%, the ratio of ω-6/ω-3 was 0.919,EPA and DHA was 11.672% in the muscle of S.scherzeri in upstream area. The essential fatty acid occupied 9.571%, the ratio of ω-6/ω-3 was 0.781,EPA and DHA was 12.939% in the muscle of S.scherzeri in downstream area. In conclusion,the nutritive value of fatty acid in the muscle of S.scherzeri in upstream area was better than that of S.scherzeri in downstream area.
