对中国沿海6种海马的生化组成进行了分析。粗蛋白含量海马、三斑海马、凯洛吉海马、棘突海马、histrix海马和海马的干重百分比分别为70.70 ± 2.12%、77.59 ± 1.06%、78.31 ± 1.74%、71.15 ± 1.32%、68.07 ± 1.96%，和76.59 ± 3.25%。海马的主要氨基酸（> 5%）为精氨酸、天冬氨酸、谷氨酸、丙氨酸和甘氨酸，6种海马的必需氨基酸（EAA）含量差异显著（P < 0.05）。6种海马的必需氨基酸指数分别为41.63、40.89、44.84、39.60、39.31和45.45。6种海马的增味氨基酸含量普遍较高，最高为28.16 ± 1.12%; histrix在H. Kelloggi法（P < 0.05）。总脂质含量通常较低，在H. histrix至2.02 +/- 0.24%。来了最丰富的脂肪酸是C16：0，在H中的范围为15.04 +/- 0.67%。trimaculatus为31.04 ± 4.32%。最小棘突二十碳五烯酸和二十二碳六烯酸的组合占总脂肪酸的比例较高（0.14-0.35）。多不饱和脂肪酸/饱和脂肪酸的比值在H. kuda为1.19;希斯特里克斯。海马体内的微量金属浓度普遍较低。研究的六种海马为人类提供了低脂肪、高蛋白、高水平的EAA和高有益微量元素的食物来源。本研究结果对开发海马养殖饲料具有重要的参考价值。
The biochemical composition of six seahorse species from the Chinese coast was analyzed in this study. The crude protein content (% dry weight) of Hippocampus kuda, Hippocampus trimaculatus, Hippocampus kelloggi, Hippocampus spinosissimus, Hippocampus histrix, and Hippocampus comes was 70.70 +/- 2.12%, 77.59 +/- 1.06%, 78.31 +/- 1.74%, 71.15 +/- 1.32%, 68.07 +/- 1.96%, and 76.59 +/- 3.25%, respectively. The major amino acids (> 5% of the total) in seahorses were arginine, aspartic acid, glutamic acid, alanine, and glycine, and there were significant differences in essential amino acids (EAA) (as % of total protein) among the six species (P < 0.05). The scores of EAA were balanced in the seahorse species, and the essential amino acid indexes of the six species were 41.63, 40.89, 44.84, 39.60, 39.31 and 45.45, respectively. The content of flavor-enhancing amino acids of the six seahorse species was generally high, ranging from 28.16 +/- 1.12% in H. histrix to 32.90 +/- 2.17% in H. kelloggi (P < 0.05). The total lipid content was generally low, ranging from 0.96 +/- 0.08% in H. histrix to 2.02 +/- 0.24% in H. comes. The most abundant fatty acid was C16:0, ranging from 15.04 +/- 0.67% in H. trimaculatus to 31.04 +/- 4.32% in H. spinosissimus. The combination of eicosapentaenoic acid and docosahexaenoic acid as the fraction of the total fatty acids was high (0.14-0.35). The polyunsaturated fatty acid/saturated fatty acid ratio ranged from 0.40 in H. kuda to 1.19 in H. histrix. The trace metal concentrations in the seahorses were generally low. The six seahorse species examined provide a food source for humans with low fat, high protein, good levels of EAA, and high beneficial trace elements. These results are valuable in developing diets for culturing seahorse species.
