摘要
采用常规营养物质测定方法,测定鲤鱼鱼卵和青鱼鱼卵的基本营养成分、氨基酸种类及含量并对其评价,利用气相色谱-质谱联用仪(GC-MS)对2种鱼卵脂肪酸组成进行分析。结果显示,2种鱼卵经真空冷冻干燥,其水分分别为3.56%±0.23%和4.55%±0.11%,青鱼鱼卵粗脂肪(4.18%±0.45%)高于鲤鱼鱼卵(2.49%±0.09%),2种鱼卵粗蛋白均高于80%,鲤鱼鱼卵粗灰分(4.80%±0.05%)高于青鱼鱼卵(4.69%±0.18%);2种鱼卵第一限制氨基酸均为缬氨酸,鲤鱼鱼卵必需氨基酸指数(60.29%)高于青鱼鱼卵(59.09%);青鱼鱼卵共检测出16种脂肪酸,鲤鱼鱼卵共检测出17种脂肪酸,共同脂肪酸有13种,两种鱼卵富含n-3多不饱和脂肪酸(EPA和DHA),其中青鱼鱼卵相对百分含量为36.14%±0.29%,而鲤鱼鱼卵为24.29%±1.22%。研究结果表明,2种淡水鱼鱼卵营养价值高,极具开发利用价值,为开发利用2种鱼卵资源提供试验依据及基础资料。
The basic nutritional components,amino acid species and content of carp roe and piceus roe were determined by routine nutritional determination methods,and the fatty acids of the two kinds of fish roe were analyzed by gas chromatography-mass spectrometry(GC-MS).The results showed that the moisture in carp roe and piceus roe was 3.56%±0.23%and 4.55%±0.11%,respectively.Crude fat content of piceus roe(4.18%±0.45%)was higher than carp roe(2.49%±0.09%).The crude protein content of both fish roe was higher than 80%.Crude ash content of carp roe(4.80%±0.05%)was higher than piceus roe(4.69%±0.18%).The first limiting amino acid of both fish roe was valine,and the essential amino acid index(60.29%)of carp roe was higher than piceus roe(59.09%).Sixteen fatty acids and thirteen common fatty acids were detected in two fish roe.Two types of fish roe are rich in n-3 polyunsaturated fatty acids(EPA and DHA),among which the content of piceus roe was up to 36.14%±0.29%,while that of carp roe was 24.29%±1.22%.The results provided experimental basis and basic data for the further development and utilization of two kinds of fish roe.
