將美洲大赤魷 (Giant squid, Dosidicus gigas) 分為頭足、胴身及尾鰭三部份進 行化學成分之測定。結果顯示不同部位的差異很小。其水分、粗蛋白、粗脂肪、灰分及 熱量分別為84.97～86.94%、12.75～13.37%、0.29～0.34%、0.81～1.01% 及 54～56 Kcal/100 g。由胺基酸組成顯示該魷魚蛋白質中富含必需胺基酸。脂肪酸組成中的飽和 脂肪酸、單不飽和脂肪酸及多不飽和脂肪酸分別為73.20～75.65% 、9.67～10.98%及 13.92～15.82%。粗脂肪中的膽固醇濃度高達13923.0～16074.8 mg/100 g，但是，由於 美洲大赤魷的粗脂肪含量非常低，經換算後，肌肉中的膽固醇含量僅有44.6～60.6 mg/100 g。

The chemical composition of head-arm, mantle and fin of giant squid, Dosidicus gigas, was analyzed. There were no distinct differences among samples in the proximate composition, composition profiles of amino acid and fatty acid and cholesterol content. The moisture, crude protein, crude fat, ash and calorie content were 85.0～86.9%, 12.8～13.4%, 0.3%, 0.8～1.0% and 54～56 Kcal/100 g, respectively. According to the amino acid analysis, the protein of these samples was rich in essential amino acids. The percentage ratios of saturated, monooic and polyoic acids in total fatty acids were 73.2～75.7%, 9.7～11.0% and 13.9～15.8%, respectively. Cholesterol was 13.9 ～16.1 g/100 g of crude fat or 44.6～60.6 mg/100 g of meat. Key words: Giant squid Dosidicus gigas, Proximate composition, Amino acid profile, Fatty acid profile, Cholestrol
