采用生物化学方法测定和分析了驼背鲈(Cromileptes altivelis)肌肉的营养成分.结果显示,每100 g驼背鲈肌肉的干物质含量:粗蛋白为84.51 g、粗脂肪为5.28 g、VE为5.59 mg、VB2为0.61 mg、钙为69.60 mg、磷为757 mg、钾为1 490 mg、钠为142 mg、铁为1.05 mg、硒为0.21 mg,钙/磷含量比为1/10.88.驼背鲈肌肉的营养成分属于高蛋白低脂肪类型,肌肉的必需氨基酸模式3 001.31 mg/g优于FAO-WHO的理想模式2 190 mg/g,氨基酸的支/芳值为2.41接近正常人体的水平,氨基酸含量(97.49%)、必需氨基酸含量(48.33%)和鲜味氨基酸含量(37.37%)均较高,氨基酸种类齐全,肉味鲜美,不饱和脂肪酸含量(13.61%)较低.结果表明,驼背鲈肌肉具有较高的营养价值,属于一种优质的海产蛋白源.
The results showed that the dry matter content of muscle of Cromileptes altivelis per 100 g: crude protein was 84.51 g, crude fat was 5.28 g, VE was 5.59 mg, VB2 was 0.61 mg, calcium was 69.60 mg, phosphorus was 757 mg, potassium was 1490 mg, sodium was 142 mg, iron was 1.05 mg, selenium was 0.21 mg, and calcium / phosphorus content was 1 / 10.88. Nutritional components belong to the high protein and low fat type. The essential amino acid pattern 3 001.31 mg / g of muscle is better than the ideal model 190 190 mg / g of FAO-WHO, the amino acid branch number / aromatic value is 2.41 close to that of normal human body, 97.49%), essential amino acid content (48.33%) and umami amino acid content (37.37%) were higher, the amino acid variety was complete, the meat flavor was delicious and the content of unsaturated fatty acid was lower (13.61%). Higher nutritional value, belonging to a high-quality seafood protein source.
