中文摘要:
      为了解主要淡水鱼鱼鳞的营养特性,以郑州市区养殖的鲫鱼、草鱼、鲤鱼和鲢鱼的鱼鳞(干基)为样品, 分别采用凯氏定氮法、反相高效液相色谱法、索氏抽提法和气相色谱法测定了鱼鳞中粗蛋白、氨基酸,粗脂肪和脂肪 酸的含量。结果表明:鲫鱼、草鱼、鲤鱼和鲢鱼的鱼鳞干基的粗蛋白含量依次为56.3%、67.3%、75.9%和76.2%,粗脂肪 含量依次为1.92%、1.34%、2.55%和1.08%,甘氨酸含量依次为12.84%、15.44%、18.19%和19.02%。亚油酸含量依次为 71.15、196.39、117.19 和136.65 mg/kg。郑州市区主要淡水鱼的鱼鳞营养物质丰富,具有一定开发利用价值。
英文摘要:
      To study the nutritional characteristics of the main breeding freshwater fish scale in Zhengzhou city, taking the fish scales(dry basis) of crucian carp, grass carp, carp and silver carp as samples, and the crude protein ,amino acids, crude fat and fatty acid content were measured by using the Kjeldahl method, reversed-phase high performance liquid chromatography, Soxhlet extraction and gas chromatography method. The results showed that the contents of crude protein of crucian carp, grass carp, carp and silver carp scales were 56.3%, 67.3%, 75.9% and 76.2% respectively. Crude fat content were 1.92%, 1.34%, 2.55% and 1.08%, respectively. The scales contained 17 kinds of amino acids, and the glycine contents were 12.84%, 15.44%, 18.19% and 19.02% respectively. The contents of linoleic acid were 71.15, 196.39, 117.19 and 136.65 mg/kg, respectively. Therefore, scales of the main freshwater fish in Zhengzhou city mainly rich in nutritional value, so it has important development and utilization value.
