Composition analysis and evaluation of Goosefish liver nutrition
-
摘要: 本文对鮟鱇鱼鱼肝的一般营养成分、氨基酸、脂肪酸、无机盐、维生素等进行了检测与营养价值评定。采用气相色谱-质谱法（GC/MS）,高效液相色谱法（HPLC）,电感耦合等离子体原子发射光谱法（ICP-AES）等方法对上述指标进行测定。鮟鱇鱼鱼肝中粗蛋白含量10.36%,总氨基酸的含量为19.04 g/100 g,含有17种氨基酸,其中必需氨基酸占总氨基酸的40.22%,鲜味氨基酸占总氨基酸的43.43%;粗脂肪达31.26%,其中多不饱和脂肪酸含量高,EPA和DHA含量分别高达15.84%和9.17%;维生素E含量为14.10 mg/100 g,维生素A的含量为2.33 mg/100 g;胆固醇的含量为1000 mg/100 g;微量元素含量丰富,但重金属的含量均低于国家标准;农药残留均在国家允许范围之内。鮟鱇鱼鱼肝具有丰富的营养价值,具有较高的开发利用价值。Abstract: The nutritional components ( general nutrients, amino acids, fatty acids, inorganic salts, vitamins, etc.) of Goosefish liver were determined, and their nutritional value was synthetically evaluated.The contents of these indices were evaluated using Gas Chromatograph-Mass Spectrometer-computer ( GC/MS) , high performance liquid chromatography ( HPLC) and Inductively coupled plasma atomic emission spectrometry ( ICP-ACE) . The results showed that the protein content of Goosefish liver was10.36%; fat was 31.26%.All samples contained 17 kinds of amino acids and the total content of amino acids was 19.04 mg/g, The essential amino acids and delicious amino acids percentages of total amino acids were 40.22% and 43.43%, respectively.It had higher content of polyunsaturated fatty acids, especially EPA and DHA content can be as high as 15.84% and 9.17%.The content of vitamin E and A were 14.10 mg/100 g and 2.33 mg/100 g. Cholesterol content was 1000 mg/100 g.Trace element content was rich, and the contents of heavy metals were lower than that of the national standard.The pesticide residues are in the national permissible range.Goosefish fish liver is rich in nutritional value, which is of great value to develop.
