| 中文摘要: |
| 目的对黄海海域砂海星(整体)进行营养成分分析,为砂海星资源的开发利用提供依据。方法采用蒽酮比色法测定总糖,用改进的索氏提取法测定粗脂肪,用气相色谱法进行脂肪酸组成分析,以微量克氏定氮法测定蛋白质含量。结果砂海星总糖含量为2.64%,还原糖含量为1.68%,脂肪含量为2.71%,其中多不饱和脂肪酸含量丰富,二十碳五烯酸(EPA)含量高,占总不饱和脂肪酸的45.077%,蛋白质含量为22.20%,化学元素含量丰富。结论砂海星营养成分含量丰富,具有很好的开发利用价值。 |
| English Summary: |
| Objective To analyse the nutritional compontents of Luidia quinaria Von Martens collected from the Yellow Sea,and to provide the theoretical bases for exploitation and utilization of its resource,.Methods The contents of total suger,crude fat and protein were determined by anthorone reagent,improved Soxhlet extraction and micro-Kjeldahl method,respectively.The analysis of fatty acid composition was determined by gas chromatography.Results The contents of total suger,reducing suger,crude fat and protein from Luidia quinaria Von Martens were 2.64%,1.68%,2.71% and 22.20%,respectively.Unsaturated fatty acid was rich in the Luidia quinaria Von Martens,especially EPA was 45% of the total(li-)pid,and chemical elements were rich.Conclusion Luidia quinaria Von Martens was rich in nutritional constituents and was worthy to be utilized. |
