| 摘 要： | 比较分析了雌雄红鳍鲌（Culter erythropterus）可食部分的基本营养成分。结果显示,雌、雄红鳍鲌肌肉的粗蛋白质量分数差异不显著（P〉0.05）,雌性性腺和鳔鲜样中粗蛋白质量分数（28.24%和19.22%）极显著高于雄性（24.89%和17.72%;P〈0.05）,雌、雄性红鳍鲌各组织的水分质量分数无显著差异（P〉0.05）;红鳍鲌各样品中均测出18种氨基酸,其中雌性性腺和鳔的氨基酸总量、必需氨基酸总量及风味氨基酸总量均显著高于雄性（P〈0.05）,雌、雄性红鳍鲌肌肉氨基酸组成差异不显著（P〉0.05）;雌雄红鳍鲌肌肉、性腺的必需氨基酸组成均符合FAO/WHO对于膳食蛋白质营养评价理想模式,但鳔的必需氨基酸组成不符合。研究表明,红鳍鲌肌肉和性腺蛋白质的营养价值较高,而鳔的蛋白质营养价值较低。

| Abstract: | We compared the nutritive components in the edible tissues of male and female Culter erythropterus.The results reveal that no significant difference is found in the content of crude protein in the muscle between male and female（P〉0.05）,but the content of crude protein in gonads and air bladder is significantly higher in female（28.24%,19.22%） than in male（24.89%,17.72%）（P〈0.05）;there is no significant difference in the content of moisture in the edible tissues between male and female（P〉 0.05）.Eighteen amino acids were discovered in the edible tissues of both male and female.The contents of total amino acids,essential amino acids and flavour amino acids in the gonads and air bladder of female are significantly higher than those of male（P〈0.05）,but there is no significant difference in amino acid composition in the muscle between male and female（P〉 0.05）.The composition of essential amino acids in the gonads and air bladder of male and female C.erythropterus meets the standard of Food and Agriculture Organization of the United Nations/Word Health Organization（FAO/WHO）,but that in the muscle does not.It is indicated that the muscle and the gonads of C.erythropterus are more nutritive,while the air bladder has relatively low nutritional value. |
