| Abstract: |
| In this paper, the nutritive composition in the muscle of Octopus minor was analyzed. The contents of crude protein, crude lipid and ash were 14.85%(71.8% in dry), 0.41% (2.0% in dry), and 1.94% (9.36% in dry), respectively; and the content of water was 79.30%. There were 17 kinds of amino acids. The total content of amino acids was determined to be 651.7 mg per gram of dry matter, in which the content of essential amino acids was 256.5 mg per gram, making up 39.36% of total amino acids. Every AAS was more than 53. Cys+Met had the lowest AAS, which was 53.14 in essential amino acids. Trp had the highest AAS, which was 217. The ten kinds of main fatty acids were assayed. The contents of EPA+DHA were 31.23% (♀) and 32.10% (♂), respectively. In addition, O. minor was rich in 11 minerals, such as Na, K, Ca, Mg, and Fe. The highest trace mineral element was Zn, which was 111.36 mg per kg. Vitamins A and B were also rich. |
