摘　　要：探究美丽华沙鳅肌肉营养成分并评价其营养品质。采用生化分析方法测定了美丽华沙鳅肌肉的营养成分并评价了其营养品质。美丽华沙鳅肌肉中一般营养成分含量占比依次为水分77.05%±1.24%、粗蛋白16.53%±0.13%、粗脂肪1.10%±0.02%、粗灰分1.47%±0.04%;共检测出氨基酸16种,其中必需氨基酸7种、非必需氨基酸9种、鲜味氨基酸4种;根据氨基酸评分和化学评分,其肌肉第一限制性氨基酸为缬氨酸,必需氨基酸指数为70.57,F值为2.15;共检测出脂肪酸23种,其中饱和脂肪酸7种、单不饱和脂肪酸5种、多不饱和脂肪酸11种,EPA含量2.31%±0.09%,DHA含量4.19%±0.83%;共检测出10种矿质元素,常量和微量元素各5种。其中钾含量最高,硒含量最低且达到富硒标准。美丽华沙鳅是一种营养含量丰富且均衡,味道鲜美的优质蛋白食物,建议在后续人工养殖中添加缬氨酸以维持其氨基酸平衡,促进鱼类健康生长。The paper aims to study the nutritional components of Sinibotia pulchra and comprehensively evaluate the nutritional value.Biochemical analysis methods were used to determine the nutritional components,and the nutritional value was comprehensively evaluated.The contents of water,crude protein,crude fat and crude ash in the muscle of S.pulchra were 77.05%±1.24%、16.53%±0.13%、1.10%±0.02%and 1.47%±0.04%.A total of 16 amino acids were detected,including 7 essential amino acids,9 non-essential amino acids and 4 umami amino acids.According to the amino acid score and chemical score,the first limiting amino acid of the muscle was valine,the essential amino acid index was 70.57,and the F value was 2.15.A total of 23 fatty acids were detected,including 7 saturated fatty acids,5 monounsaturated fatty acids,and 11 polyunsaturated fatty acids.The contents of EPA and DHA in fatty acids were 2.31%±0.09%and 4.19±0.83%,respectively.A total of 10 mineral elements were detected,including 5 major elements and 5 trace elements.Among them,the potassium content was the highest,and the selenium content was the lowest and reached the selenium-enriched standard.S.pulchra is a high-quality protein food with rich and balanced nutrition and delicious taste.It is suggested that valine should be added to maintain its amino acid balance and promote the healthy growth of S.pulchra.
