摘要
目的:分析和评价弯斑蛸可食部分、生殖腺、肝和胰脏的主要营养特性,并对可食部分的氨基酸、脂肪酸、维生素、矿物元素进行分析和营养评价。方法:用常规方法分析其主要营养素;用氨基酸分析仪分析氨基酸组成,并采用FAO/WHO推荐的蛋白质模式对蛋白质进行营养评价;脂肪酸用气相色谱-质谱联用仪进行检测,并通过分析其组成的主要指标来评价其营养价值;维生素和矿物元素含量直接说明其营养功能。结果:可食部分粗蛋白质含量最高,为78.9%,蛋白质营养价为97,总糖含量肝胰脏>生殖腺>可食部分;脂肪酸中的PUFA和HUFA含量分别为52.6%和51.1%;维生素A和维生素E含量较高;钾、磷、钙、镁、铁等元素的含量丰富。结论:弯斑蛸是高蛋白、低脂肪,蛋白质营养价值高,脂肪酸和矿物元素含量较高的海洋食品。
Objective： To analyze and evaluate the main nutrients of edible part, germen, liver and pancreas of Octopus dollfusi. Method： The main nutrients were determined with routine methods. Amino acid compositions were determined with amino acid analyzer. Fatty acid compositions were inspected with GC-MS. Results： Crude protein content of the edible part was highest （78.9%）, with chemical score 97. The order of total sugar content was liver and pancreas〉germen〉edible part. The content of polyunsaturated fatty acid （PUFA） and long- chain PUFA （LCPUFA） in total fatty acid was 52.6% and 51.1% respectively. The content of vitamin A and vitamin E was higher, and the contents of potassium, phosphorus, calcium, magnesium, iron, etc. were rich. Conclusion： Octopus dollfusi is a seafood with higher protein and lower fat, very high protein nutritive value, more fatty acid and mineral elements, and is good for health.
