摘要:

采用氨基酸全自动分析仪、气质联用仪、电感耦合等离子体发射光谱仪、原子荧光分光光度计等对速冻蟹黄粉的粗蛋白、氨基酸、粗脂肪、脂肪酸、矿物质元素的含量进行了测定,并分析评价速冻蟹黄粉的各种营养成分。结果表明:速冻蟹黄粉粗蛋白质含量为15.61%,至少含有16 种氨基酸,必需氨基酸含量较高,占氨基酸总量的37.61%,4 种致鲜氨基酸占氨基酸总量52.40%;粗脂肪含量为45.09%,不饱和脂肪酸含量丰富,占脂肪酸总量的8 7 . 00%;矿物质含量也较高,尤其是钙、磷、铁、锌、硒。因此,速冻蟹黄粉具有较高的食用与营养价值,是生产保健食品的良好天然资源,值得进一步开发利用。

Abstract:

Compositions of crude protein, amino acids, crude fat, fatty acids and mineral elements in fast-frozen crab yolk powder were analyzed and evaluated using amino acid automatic analyzer, gas chromatography/mass spectrometer (GC-MS), inductive coupled plasma emission spectrometer (ICP) and atomic fluorescence spectrophotometer. The content of crude protein in samples was 15.61%, which contained at least 16 kinds of amino acids. Essential amino acids were determined to be 37.61% of total amino acids. Furthermore, the content of 4 delicious amino acids was 52.40%. The content of crude fat in samples was 45.09%. Unsaturated fat acids were rich in samples and reached up to 87.00%. Mineral elements especially for Ca, P, Fe, Zn and Se in samples also exhibited a higher level. Therefore, fast-frozen crab yolk powder is one of high-quality foods with higher edible and nutrition value. It is also good natural sources for healthy food, and worthy of further exploitation and utilization.
