| 摘 要： | 利用常规肌肉生化成分测试方法测定了中国鲳成鱼和幼鱼肌肉的一般生化成分、氨基酸和脂肪酸含量。结果表明,中国鲳成鱼和幼鱼肌肉中的一般生化成分均具有显著性差异。除水分外,成鱼肌肉的粗灰分、粗蛋白和粗脂肪含量均显著性高于幼鱼(P<0.05)。中国鲳成鱼和幼鱼肌肉中含有包括色氨酸和牛磺酸在内的18种氨基酸,总量分别为78.68%和72.92%(质量分数,干样),其中包括人体必需氨基酸8种,总量分别为33.26%和31.05%,分别占氨基酸总量的42.28%和42.58%;中国鲳成鱼和幼鱼的必需氨基酸组成比例基本符合FAO/WHO的标准。中国鲳成鱼和幼鱼的限制性氨基酸均为色氨酸和蛋氨酸+胱氨酸,必需氨基酸指数分别为62.16和77.68,4种鲜味氨基酸含量分别为28%和26.44%(干样)。中国鲳成鱼和幼鱼肌肉中脂肪酸种类丰富,成鱼肌肉含有饱和脂肪酸(SFA)7种,单不饱和脂肪酸(MUFA)5种,多不饱和脂肪酸(PUFA)8种;而幼鱼肌肉中SFA8种,MUFA6种,PUFA7种。中国鲳成鱼和幼鱼肌肉中EPA含量较低,分别占肌肉脂肪酸的2.49%和4.86%;而DHA较高,分别占肌肉脂肪酸的10.26%和16.23%。中国鲳成鱼和幼鱼必需氨基酸的A/E值较为接近,大小顺序均为:赖氨酸>亮氨酸>精氨酸>缬氨酸>异亮氨酸>苏氨酸>苯丙氨酸>蛋氨酸>组氨酸>色氨酸。

| Abstract: | Biological components,amino acid and fatty acid composition in muscles of young and adult P.chinensis were tested and analyzed with routine methods.The results showed that there were significant differences in proximate composition between young and adult fish.Except moisture content,the content of crude ash,crude protein and crude lipid in muscles of adults were significantly higher than those of young fish(P<0.05).Muscles of young and adult P.chinensis included 18 common amino acids and 8 essential amino ... |
