摘要
测定8尾红罗非鱼的含肉率及氨基酸组成。结果表明,红罗非鱼的含肉率平均为66.46％;干物质中水解氨基酸总量为84.14％,其中必需氨基酸为35.59％,占氨基酸总量的42.30％;游离氨基酸总量为799.59mg/100g,6种呈味氨基酸的总量为608.74mg/100g,占游离氨基酸总量的76.13％;限制氨基酸为蛋+胱氨酸,必需氨基酸指数为54.67,认为红罗非鱼是一种营养价值和养殖价值都较高的品种。
The rate of flesh content and compositions of amino acids of Oreochromis niloticus×O. mossambicus were determined. The results showed that the rate of flesh content of Oreochromis niloticus×O. mossambicus was 66.46%. The amount of hydrolytic amino acids was 84.14%, in which the content of essential amino acids was 35.59 %, making up 42.30 % of total amino acids. The content of free amino acids was 799.59mg/100g, in which the content of 6 tasty amino acids was 608.74mg/100g, making up 76.13 % of total free amino acids. The limited amino acids were MET and CYS, the EAAI was 54.67. In conclusion, Oreochromis niloticus×O. mossambicus is one of fishes with better nutritive value and raising value.
