摘要
试验旨在探究人工繁殖饲养的云南吻孔鲃肌肉营养成分,测定了云南吻孔鲃肌肉常规营养成分、氨基酸组成、脂肪酸组成和矿质元素。结果表明,云南吻孔鲃肌肉(鲜样)中水分、粗蛋白、粗脂肪和灰分含量分别为78.05%、17.16%、2.22%和1.13%。云南吻孔鲃肌肉中共检出17种氨基酸,氨基酸总量为(13.98±0.30)%,必需氨基酸所占比例为(5.80±0.05)%,非必需氨基酸所占比例为(8.18±0.26)%,鲜味氨基酸所占比例为(5.28±0.33)%,必需氨基酸总量符合FAO/WHO推荐的理想蛋白标准,第一限制氨基酸为蛋氨酸+胱氨酸,必需氨基酸指数为75.77。云南吻孔鲃肌肉中共检出15种脂肪酸,总不饱和脂肪酸相对含量为64.13%,以C18系列为主,油酸含量最高,为(43.32±9.43)%。常量元素中,云南吻孔鲃肌肉钾(K)含量最高,为(3 516.00±82.73) mg/kg;镁(Mg)含量最低,为(319.04±15.58)mg/kg。微量元素中,云南吻孔鲃肌肉铁(Fe)的含量最高,为(18.35±6.28) mg/kg;锰(Mn)含量最低,为(0.12±0.02) mg/kg。研究表明,云南吻孔鲃是一种富含氨基酸、脂肪酸、矿质元素且营养均衡的膳食鱼类,其在作为高油酸膳食方面具有较高的开发和应用前景。
The purpose of the experiment was to explore the nutritional components of muscle of artificially propagated Yunnan Poropuntius hangchuchieni.Routine nutrient composition,amino acid composition,fatty acid composition,and mineral elements in muscle of Yunnan Poropuntius hangchuchieni were determined.The results showed that the contents of water,crude protein,crude fat and ash in muscle(fresh sample)were 78.05%,17.16%,2.22%and 1.13%,respectively.Seventeen amino acids were detected.The total amino acid content was(13.98±0.30)%,the essential amino acid content was(5.80±0.05)%,the non-essential amino acid content was(8.18±0.26)%,and the flavor amino acid content was(5.28±0.33)%.The total essential amino acid content was in accordance with the ideal protein standard recommended by FAO/WHO.The first restricted amino acid was methionine+cystine,and the essential amino acid index was 75.77.Fifteen kinds of fatty acids were detected,the relative content of total unsaturated fatty acids was 64.13%,C18 series was the main one,and the content of oleic acid was the highest,which was(43.32±9.43)%.Among the major elements,the content of potassium(K)was the highest,which was(3516.00±82.73)mg/kg,and the content of magnesium(Mg)was the lowest,which was(319.04±15.58)mg/kg.Among the trace elements,the content of iron(Fe)was the highest,which was(18.35±6.28)mg/kg,and the content of manganese(Mn)was the lowest,which was(0.12±0.02)mg/kg.The study indicates that Yunnan Poropuntius hangchuchieni is a kind of dietary fish with rich amino acids,fatty acids and mineral elements and balanced nutrition,and it has a high development and application prospect as a high oleic acid diet.
