摘　　要：对察尔森水库青虾(Macrobrachium nipponense)营养成分进行了分析及评价。结果表明:察尔森水库青虾中水分、粗蛋白、粗脂肪、灰分和总糖含量分别为79.13%、16.47%、1.02%、1.25%和0.25%。察尔森水库青虾共检出18种氨基酸,其中必需氨基酸(EAA)8种,非必需氨基酸(NEAA)10种,总氨基酸(TAA)含量为76.99%,EAA含量为28.92%,NEAA含量为48.07%。EAA/TAA为37.56%,EAA/NEAA为60.16%,EAA/TAA接近而EAA/NEAA超过FAO/WHO推荐标准。根据氨基酸评分(AAS)和化学评分(CS)第一限制性氨基酸是苏氨酸(Thr),而第二限制性氨基酸就氨基酸评分来说是缬氨酸(Val);就化学评分来说是苯丙氨酸+酪氨酸(Phe+Tyr)。察尔森水库青虾肌肉脂肪中检测到17种脂肪酸,其中饱和脂肪酸(SFA)5种,含量为20.44%;单不饱和脂肪酸(MUFA)3种,含量为33.80%;多不饱和脂肪酸(PUFA)9种,含量为26.35%;EPA含量为11.83%,DHA含量为5.81%。研究结果表明,察尔森水库青虾是一种营养价值较高的虾类,尤其是EPA和DHA含量高,常食有利于人体健康。The nutritional constituents of Macrobrachium nipponense in Charsen Reservoir were analyzed and evaluated.The results showed that the contents of water,crude protein,crude fat,ash and total sugar were 79.13%,16.47%,1.02%,1.25% and 0.25%,respectively.A total of 18 amino acids were detected in Macrobrachium nipponense,including 8 essential amino acids(EAA) and 10 non-essential amino acids(NEAA).The content of TAA was 76.99%,EAA 28.92% and NEAA 48.07%.EAA/TAA was 37.56%,EAA/NEAA was 60.16%,EAA/TAA was close to but EAA/NEAA exceeded the FAO/WHO recommended standard.According to the amino acid score(AAS) and chemical score(CS),the first limiting amino acid is threonine(Thr),while the second limiting amino acid is valine(Val) for amino acid score and phenylalanine + tyrosine(Phe+Tyr) for chemical score.17 kinds of fatty acids were detected in muscle fat of Macrobrachium nipponense in Charsen Reservoir,including 5 kinds of saturated fatty acids(SFA),the content of which was 20.44%.3 kinds of monounsaturated fatty acids(MUFA),the content of 33.80%;9 kinds of polyunsaturated fatty acids(PUFA),the content of 26.35%;EPA content was 11.83% and DHA content was 5.81%.The results show that the Macrobrachium nipponense from Qasen reservoir is a kind of Macrobrachium nipponense with high nutritional value,especially the content of EPA and DHA,and regular eating is beneficial to human health.
