摘要: 对野生和养殖大鳞副泥鳅(Paramisgurnus dabryanus)营养成分分别进行了测定。结果表明,野生大鳞副泥鳅水分、灰分、脂肪、蛋白质的含量分别为77.30%、1.30%、1.10%、18.10%,养殖大鳞副泥鳅分别为71.80%、1.10%、5.30%、17.20%;18种氨基酸总量野生为17.40%、养殖为15.50%,色氨酸、苯丙氨酸和甘氨酸于养殖个体中稍高于野生个体,其他15种氨基酸均以野生个体的含量稍高;人体必需氨基酸和鲜味氨基酸含量均以野生个体的略高,分别为8.03%和6.47%,养殖个体的分别为6.84%和6.02%;野生和养殖大鳞副泥鳅的不饱和脂肪酸分别占脂肪酸总量的67.13%、77.39%,其中多不饱和脂肪酸分别为27.39%和41.65%,DHA+EPA分别占脂肪酸总量的4.20%和1.59%。

Abstract: The nutrient compositions of wild and farmed P. dabryanus were analyzed. The results showed that the water content, ash, crude fat and crude protein of wild P. dabryanus were 77.30%, 1.30%, 1.10% and 18.10%, respectively, and those of farmed P. dabryanus were 71.80%, 1.10%, 5.30% and 17.20%, respectively. The total of 18 amino acids was 17.40% in wild individuals and 15.50% in farmed individuals. In which, Tryptophan, Phenylalanine and Glycine in farmed individuals were slightly higher than those in wild individuals, and the other 15 amino acids were higher in wild individuals. The contents of essential amino acids for human and the delicious amino acids in wild individuals were 8.03% and 6.47% respectively, higher than those in farmed individuals which were 6.84% and 6.02%. The unsaturated fatty acids accounted for 67.13% and 77.39% of the total fatty acids in wild and farmed P. dabryanus, in which the polyunsaturated fatty acids in wild and farmed P. dabryanus were 27.39% and 41.65%, the DHA+EPA accounted for 4.20% and 1.59% of the total fatty acids respectively.

Key words: Paramisgurnus dabryanus, nutrient composition, amino acids, fatty acids
