Abstract:

The nutritive components of Pollicipes mitella were determined,its nutritional quality was also evaluated synthetically. Its crude protein,crude fat,ash,moisture and Nitrogen Free Extract (NFE) of the fresh muscle was 19.28%,2.54%,1.47%,74.47%,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. the amount of total delicious amino acids was6.77%.The fatty acids contained 39.77% high unsaturated fatty acids (HUFA),in which the content of EPA,DHA were 13.37%, 20.67% respectively. There was a high content of minerals in the muscle of Pollicipes mitella. Especially for Mg,Ca,Fe,Zn,Se,their contents was 1625.49、679.82、38.89、112.25、1.78μg•g-1 respectively.In conclusion,the muscle of Pollicipes mitella has very high nutritive and care value.
