摘　　要：以新吉富罗非鱼、尼罗罗非鱼、奥利亚罗非鱼为研究对象,采用生化分析方法,综合分析和评价了其肌肉成分组成和营养价值。结果显示:3种罗非鱼肌肉中粗蛋白含量20.00%~21.00%,粗脂肪含量1.30%~2.35%;共检测出17种氨基酸,其中必需氨基酸含量为8.34%~8.61%,占所含氨基酸总量44.10%~44.43%,与非必需氨基酸比值为87.62%~89.41%,高于联合国粮食及农业组织/世界卫生组织的优质蛋白质评价标准;其肌肉中含有20种脂肪酸,其中多不饱和脂肪酸占19.65%~23.71%,比例高于大部分肉类、奶、蛋及一些常见水产品。指出,3种罗非鱼各有特点,均为高蛋白低脂肪、肉质鲜美、营养价值较高的优质淡水鱼类。The muscle composition and nutritional value of NEW GIFT Oreochromis Niloticus,Oreochromis Niloticus,and Oreochromis aureus were analyzed and evaluated by biochemical methods.The results showed that their contents of crude protein and crude fat were 20.00%-21.00%and 1.30%-2.35%,respectively and they contained 17 kinds of amino acids,with essential amino acids(EAA)were 8.34%-8.61%,accounting for 44.10%-44.43%of the total amino acids.And the ratio EAA to non essential amino acids(NEAA)was 87.62%-89.41%,higher than the standard for quality protein evaluation of FAO/WHO.They contains 20 kinds of fatty acids,with polyunsaturated fatty acids account for 19.65%-23.71%,higher than most meat,milk,eggs and some common aquatic products.In conclusion,all three species of Tilapia are high protein,low fat,delicious meat and high nutritional value of high-quality freshwater fish.
