中文摘要 | 為比較養殖和野生虱目魚化學組成分之差異,針對兩者之一般成分、胺基酸及脂肪酸組成進行分析。養殖虱目魚的肥滿度顯著大於野生虱目魚 (p < 0.05);一般成分分析結果顯示養殖虱目魚之粗脂肪遠高於野生魚;相對地,水分、粗蛋白及灰分則以後者含量較高。在胺基酸組成方面,兩者均富含天門冬胺酸 (aspartic acid)、麩胺酸 (glutamic acid)、白胺酸 (leucine)、組胺酸 (histidine)、離胺酸 (lysine) 及精胺酸 (arginine)。脂肪酸組成中,養殖虱目魚的18:1和18:2高於野生魚,而後者則有較多之16:0、18:0、20:4、20:5及22:6。相較之下,養殖虱目魚之飽和脂肪酸 (saturates) 較低而單不飽和脂肪酸 (monoenes) 較高,兩者的多不飽和脂肪酸 (polyenes) 則無顯著差異。 |
英文摘要 | The proximate composition, amino acid composition, and fatty acid composition of cultured and wild milkfish (Chanos chanos) were analyzed and compared. The condition factor of cultured fish was significantly (p < 0.05) higher than that of wild fish. The crude fat content in cultured fish was higher, but the moisture, crude protein, and ash contents were lower than those of wild fish. The amino acid composition showed that both cultured and wild fish were rich in aspartic acid, glutamic acid, leucine, histidine, lysine, and arginine. The fatty acid composition of lipids differed between cultured and wild fish. Cultured fish had higher levels of 18:1 and 18:2 fatty acids, but wild fish had higher levels of 16:0, 18:0, 20:4, 20:5, and 22:6 fatty acids. The cultured fish had a higher amount of monoenes, but were lower in saturated fatty acids. Polyenes showed no significant differences between cultured and wild fish. |
