研究秀丽高原鳅肌肉营养成分和评价肌肉营养价值,为其开发利用与人工养殖提供参考依据,为开展相关配合饲料研究积累资料。2013年12月从云南省鹤庆县龙潭采集秀丽高原鳅野生个体,随机抽取30尾成鱼作为实验用鱼,体长(8.00±1.16)cm、体重(6.27±3.19)g。用常规方法测定分析了30尾秀丽高原鳅肌肉的营养成分组成与含量,并对其营养价值进行了综合评价。结果显示,秀丽高原鳅肌肉中水分、粗蛋白质、粗脂肪和粗灰分的含量分别为70.92%、24.10%、3.73%和1.25%;共检测出18种氨基酸,氨基酸总量为13.64%;包括8种人体必需氨基酸和10种非必需氨基酸,所占比例分别为5.98%与7.66%;第一限制性氨基酸为色氨酸,必需氨基酸指数为48.11;鲜味氨基酸占氨基酸总量的30.94%。主要含有16种脂肪酸,其中多不饱和脂肪酸含量为32.11%,EPA与DHA总含量为11.68%;常量元素中磷的含量最高(786.60×10~(-2)mg/g),微量元素中Mg的含量最高(14.75×10~(-2)mg/g)。秀丽高原鳅营养成分丰富均衡、味道鲜美,具有较高的食用价值与保健作用。
To study the nutritive components of muscle and evaluate the nutritional value of muscle in beauty plateau loach and to provide a reference for its development and utilization and artificial breeding and to accumulate data for the research of related compound feed. In December 2013, 30 wild individuals of Misato dappilli were collected from Longtan, Heqing County, Yunnan Province. 30 adult fish were selected as test fish, body length (8.00 ± 1.16) cm and body weight (6.27 ± 3.19) g. The composition and content of nutrients in the muscle of 30 Caucasus anguillarum were analyzed by conventional methods, and their nutritional value was evaluated comprehensively. The results showed that the contents of water, crude protein, crude fat and crude ash in the muscle of Beech toachlet were 70.92%, 24.10%, 3.73% and 1.25% respectively. A total of 18 kinds of amino acids were detected and the total amount of amino acids was 13.64% The essential amino acids and the essential amino acids accounted for 5.98% and 7.66% respectively. The first restricted amino acid was tryptophan, the essential amino acid index was 48.11, and the umami amino acid accounted for 30.94% of the total amino acids. The content of polyunsaturated fatty acids is 32.11%, the content of EPA and DHA is 11.68%, the content of phosphorus is the highest (786.60 × 10 ~ (-2) mg / g), the content of trace elements Mg The highest content (14.75 × 10 -2 mg / g). Beauty Highland loach rich and balanced nutritional content, delicious, with high food value and health effects.
