抚仙湖两种土著鱼肌肉营养成分比较分析OA
Comparative analysis of muscle nutritional composition in two indigenous fish species from Fuxian lake
试验旨在评估抚仙湖两种土著鱼类的营养特性.选取野生鱇浪白鱼、养殖鱇浪白鱼和野生云南光唇鱼为研究对象,分析其背部肌肉常规营养成分、氨基酸组成、脂肪酸组成及矿物质元素含量.结果显示,肌肉粗蛋白含量排序为野生鱇浪白鱼>野生云南光唇鱼>养殖鱇浪白鱼.3种鱼肌肉中均检出17种氨基酸,其中非必需氨基酸10种,必需氨基酸7种,呈味氨基酸6种.3种鱼谷氨酸含量均最高,分别占总氨基酸的14.85%、14.17%和15.62%.野生鱇浪白鱼肌肉中共检出18种脂肪酸,其中饱和脂肪酸5种,单不饱和脂肪酸5种,多不饱和脂肪酸8种;养殖鱇浪白鱼共检测出22种脂肪酸,其中饱和脂肪酸7种,单不饱和脂肪酸6种,多不饱和脂肪酸9种;野生云南光唇鱼共检出20种脂肪酸,其中饱和脂肪酸5种,单不饱和脂肪酸6种,多不饱和脂肪酸9种.3种鱼不饱和脂肪酸含量分别是67.01%、78.36%和64.44%,均以油酸和二十二碳六烯酸(DHA)为主.野生鱇浪白鱼和野生云南光唇鱼矿物质元素中钾含量均最高,分别为4 430.00 mg/kg和4 550.00 mg/kg,肌肉中钾/钠分别为18.08和17.22.研究表明,鱇浪白鱼与云南光唇鱼是富含优质蛋白、必需氨基酸、有益脂肪酸和矿物质元素的营养型鱼类.
The experiment aimed to evaluate the nutritional characteristics of two indigenous fish species in Fuxian lake.Selecting wild Anabarilius grahami,farmed Anabarilius grahami,and wild Acrossocheilus yunnanensis as research objects,the conventional nutritional composition,amino acid composition,fatty acid composition,and mineral element content of their back muscles were analyzed.The results showed that the crude protein content of the muscle was ranked as follows:Wild Anabarilius grahami>wild Acrossocheilus yunnanensis>farmed Anabarilius grahami.A total of 17 amino acids were detected in the three types of fish,including 10 non essential amino acids,seven essential amino acids,and six flavor amino acids.The three types of fish had the highest content of glutamic acid,accounting for 14.85%,14.17%,and 15.62%of the total amino acid content,respectively.A total of 18 types of fatty acids were detected in the muscles of wild Anabarilius grahami,including five saturated fatty acids,five monounsaturated fatty acids,and eight polyunsaturated fatty acids.A total of 22 types of fatty acids were detected in farmed Anabarilius grahami,including seven saturated fatty acids,six monounsaturated fatty acids,and nine polyunsaturated fatty acids.A total of 20 fatty acids were detected in wild Acrossocheilus yunnanensis,including five saturated fatty acids,six monounsaturated fatty acids,and nine polyunsaturated fatty acids.The content of unsaturated fatty acids in the three types of fish was 67.01%,78.36%,and 64.44%,respectively,mainly composed of oleic acid and docosahexaenoic acid(DHA).The potassium content in the mineral elements of wild Anabarilius grahami and wild Acrossocheilus yunnanensis was the highest,at 4 430.00 mg/kg and 4550.00 mg/kg,respectively.The potassium-to-sodium ratio in the muscles was 18.08 and 17.22,respectively.The study shows that Anabarilius grahami and Acrossocheilus yunnanensis are nutritious fish species rich in high-quality protein,essential amino acids,beneficial fatty acids,and mineral elements.
