2、水化合物含量与南极磷虾差异不显著。南极冰鱼肌肉与南极磷虾均含有17种氨基酸,必需氨基酸指数分别为44.24和34.03,必需氨基酸的构成比例符合FAD/WHO的标准;鲜味氨基酸占总氨基酸的比例分别为35.86%和40.51%。南极冰鱼中饱和脂肪酸(33.37%)和单不饱和脂肪酸(41.22%)含量分别高于南极磷虾(32.60%和29.75%),南极磷虾多不饱和脂肪酸(25.12%)含量低于南极磷虾(45.38%)。南极冰鱼肌肉中的矿物质(Ca、Fe、Zn、Cu等)含量低于南极磷虾。因此,南极冰鱼具有较高的
3、营养价值和良好的开发应用前景。关键词:南极冰鱼;南极磷虾;营养成分;分析;评价文章篇号:1673-9078(2014)2-228-233ComparisonandEvaluationoftheNutritionalComponentsofAntarcticIcefishandKrillLIUZhi-dong1,CHENXue-zhong1,QUYing-hong2,FENGChun-lei1,HUANGHong-liang1,TIANLiang-liang1,LIUJian1,GONGYang-yang1
