| 中文摘要: |
| 4个野生银鲳(Pampusargenteus)群体样本于2008年5月分别采集于河北黄骅、江苏连云港、浙江舟山、广东惠来4地沿海海域,分别对其肌肉的主要营养成分进行了分析和评价。结果表明,浙江舟山与河北黄骅银鲳群体肌肉的粗蛋白含量差异显著(P<0.05),其他各群体银鲳肌肉间粗蛋白含量差异不显著。肌肉粗脂肪含量在4群体银鲳间无显著性差异(P>0.05)。氨基酸及必需氨基酸总量以江苏连云港群体肌肉中含量最高,分别占干重的65.14%和27.32%,浙江舟山群体(64.31%和26.42%)其次,河北黄骅群体(60.32%和25.47%)最低,4群体间差异显著(P<0.05)。江苏连云港及浙江舟山群体银鲳肌肉的必需氨基酸指数(EAAI)、氨基酸评分(AAS)和化学评分(CS)均高于另外2群体。4群体银鲳肌肉间饱和脂肪酸及不饱和脂肪酸总量呈现显著性差异(P<0.05)。江苏连云港及浙江舟山群体银鲳肌肉的多不饱和脂肪酸含量要高于另外2群体。综合比较,江苏连云港及浙江舟山群体银鲳肌肉的营养价值要优于河北黄骅和广东惠来群体。从银鲳4野生群体的聚类分析结果可以看出:就氨基酸含量来说,浙江舟山与江苏连云港群体差异最小,与广东惠来群体差异最大;就脂肪酸差异来讲,浙江舟山与河北黄骅群体相似性较高,与广东惠来之间的差异最大。 |

| Four wild populations of Pampus argenteus were sampled from nature coast area of Huanghua City in Hebei Province(PH),Lianyungang City in Jiangsu Province(PJ),Zhoushan City in Zhejiang Province(PZ) and Huilai City in Guangdong Province(PG),respectively.The capture was conducted in May 2008.The muscle nutritional composition of P.argenteus from 4 different areas was measured by conventional biochemistry.As a result,crude protein content in the muscle of fish from PZ and PJ was significant difference(P<0.05),while there was no significant difference in other each pair of populations.There was no significant difference in crude fat content among the four populations(P>0.05).Fish from PJ had the highest total and essential amino acid contents(65.14% and 27.32%,dry weight).The following was fish from PZ(64.31% and 26.42%,dry weight).The lowest total and essential amino acid contents(60.32% and 25.47%,dry weight) were in the muscle of fish from PH.There was significant difference of total and essential amino acid content among the four populations(P<0.05).Fish from PJ and PZ had higher essential amino acid index(EAAI)、amino acid score(AAS) and chemical score(CS) than those of the other 2 populations.The total saturated and unsaturated fatty acid contents in the fish muscle from four populations shown significant difference(P<0.05).Fish from PJ and PZ had higher polyunsaturated fatty acid content than those from other two populations.It was apparent that the nutritional quality of fish from PJ and PZ was better than those from PH and PG.Based on the clustering analysis,the difference of amino acid content in fish from PJ and PZ was smallest,while having the biggest difference with that from PG.For fatty acids,fish from PZ and PH had similar content,also had the biggest difference with that from PG. |
