| 摘 要： | 测定了龟足Pollicipes mitella柄部肌肉的营养成分，并对其营养价值进行综合评价。结果表明龟足柄部肌肉含粗蛋白19.28%、粗脂肪2.54％、灰分1.47％、水分74.47％和无氮浸出物（NEF）2.24％。17种水解氨基酸总量为18.08% ,其中7种必需氨基酸为6.63% ,必需氨基酸指数为82.63，鲜味氨基酸为6.77%。多不饱和脂肪酸的含量占总脂肪酸的39.77％,其中二十碳五烯酸(EPA)、二十二碳六烯酸(DHA)分别占总脂肪酸的13.37％和20.67％。龟足含有十分丰富的Mg、Ca、Fe、Zn、Se,含量分别为1625.49、679.82、38.89、112.25和1.78μg.g-1。因此龟足肌肉具有较高的食用价值与保健作用。

| Abstract: | The nutritive components of PoUicipes mitella were determined, and its nutritional quality was also evaluated systematically. The crude protein, crude fat, ash, moisture, and Nitrogen Free Extract (NFE) of the fresh muscle were 19.28%, 2.54%, 1.47%, 74.47%, and 2.24%, respectively. On the basis of fresh matter of the muscle, the amount to fhydrolytic amino acids was 18.08%, in which the content of essential amino acids was 6.63%, the EAAI was 82.63, and the amount of total delicious amino acids was 6.77%. The fatty acids contained 39.77% high unsaturated fatty acids (HUFA), in which the content of EPA and DHA were 13.37% and 20.67%, respectively. There was a high content of minerals in the muscle of Pollicipes mitella. Especially for Mg, Ca, Fe, Zn, and Se, their contents were 1 625.49, 679.82, 38.89, 112.25, and 1.78 μg·g~(-1),respectively. In conclusion, the muscle of Pollicipes mitella has very high nutritive and care value. |
