| 摘 要： | 本研究采用生化分析方法,对侧条厚唇鱼(Acrossocheilus parallens)肌肉常规营养成分、脂肪酸和氨基酸含量进行测定和分析,以期为侧条厚唇鱼肌肉的营养评价提供科学依据。结果表明：侧条厚唇鱼肌肉的常规营养成分中,水分、粗蛋白、粗脂肪和粗灰分含量依次为(77.20±0.42)%、(19.70±0.22)%、(3.25±0.07)%和(1.30±0.01)%;其肌肉中共检出21种脂肪酸,其中饱和脂肪酸(SFA)8种、不饱和脂肪酸(UFA)13种,UFA和必需脂肪酸(EFA)分别占比达68.07%、21.76%;其肌肉中检测出17种氨基酸,其中必需氨基酸(EAA)7种、半必需氨基酸(HEAA)2种、非必需氨基酸(NEAA)8种,EAA和鲜味氨基酸(UAA)分别占氨基酸总量的40.85%、37.55%;侧条厚唇鱼肌肉的氨基酸组成具有较好的平衡性,其必需氨基酸的氨基酸评分值(AAS)除了缬氨酸外均大于1,化学评分值(CS)均大于0.5,必需氨基酸指数(EAAI)达到86.19,蛋白质的品质较好。综上,侧条厚唇鱼的营养价值较高,是一种具有较高开发价值的优质淡水经济鱼类。

| Abstract: | To provide a scientific basis for the nutritional evaluation of Acrossocheilius parallens muscle, the contents of routine nutrition components, fatty acids and amino acids in muscle were determined and analyzed by biochemical method. The results showed that the contents of water, crude protein, crude fat and crude ash in A.parallens muscle were (77.20±0.42)%, (19.70±0.22)%, (3.25±0.07)% and (1.30±0.01)%, respectively. There were 21 kinds of fatty acids in the muscle, including 8 saturated fatty acids (SFA) and 13 unsaturated fatty acids (UFA). The proportion of UFA and essential fatty acid (EFA) was 68.07% and 21.76%, respectively. There were 17 kinds of amino acids in the muscle, including 7 essential amino acids (EAA), 2 semi-essential amino acids (HEAA) and 8 non-essential amino acids (NEAA). EAA and umami amino acid (UAA) accounted for 40.85% and 37.55% of the total amino acids, respectively. The amino acid composition of A.parallens muscle was well balanced. The amino acid score (AAS) of A.parallens muscle was more than 1 except Valine, the chemical score (CS) was more than 0.5, and the essential amino acid index (EAAI) was 86.19, indicating that the quality of protein was good. To sum up, the high nutritional value of the A.parallens is a kind of high-quality economic freshwater fish with high development value. |
