摘要: |
分析了不同规格鲆鲽类的生化组成并进行了营养价值研究和安全性评价。结果表明,不同规格的鲆鲽类鱼肉氨基酸都符合FAO/WHO公布的氨基酸理想模式:EAA/TAA含量在40%左右、EAA/NEAA在60%以上,重金属含量都符合国内外相关标准,所以鲆鲽类蛋白质都属于理想安全的优质蛋白质。不同规格鲆鲽类的FAA/TAA的比例都相近,而1~2 kg的鲆鲽类的必需氨基酸、非必需氨基酸、鲜味氨基酸含量普遍高于0.5 kg的大菱鲆。 |

The comparison of biochemical compositions and nutritional value of flatfish |
|
Abstract: |
Biochemical compositions of flatfish were analyzed,and nutritional value and safety evaluation of flatfish were discussed based on their characteristics of biochemical composition.The results showed that the animo acids of flatfish conformed to the animo acids ideal mode(EAA/TAA about 40% and EAA/NEAA above 60%)published by FAO/WHO,and the contents of heavy metals met the relevant standards home and abroad,indicating that the proteins of flatfish were ideal and quality safe.The ratios of FAA/TAA were close in different sized flatfish,but the contents of EAA,NEAA and FAA in 1~2 kg flatfish were larger than those in 0.5 kg flatfish. |
