| 摘要: |
| 本次实验选取了圣景园、天嘉湖、今珠、富兴四种不同品牌的柴鸡蛋，对其蛋清和蛋黄中的粗蛋白含量以及氨基酸组成和含量进行了测定和分析，通过氨基酸比值系数法对其营养价值进行了评定。结果表明，这四种不同品牌的柴鸡蛋氨基酸含量丰富，种类齐全，组成比例合理，其中，今珠品牌的柴鸡蛋不论是粗蛋白含量，还是氨基酸比值系数分均高于其他几种柴鸡蛋，评分达到了82.34，说明其所含的必需氨基酸的含量及相互间的组成比例与人体的需求更加接近，营养价值更高。同时也说明柴鸡蛋营养价值较高，具有广阔的市场开发和利用前景。 |

| Abstract: |
| Four different brands of firewood eggs of Sheng Jing Yuan, Tian Jia Hu, Jin Zhu and Fu Xing were selected to analyse the content of crude protein in the egg white and egg yolk. Meanwhile, the composition and content of amino acids were measured and analyzed, and the nutritional value was determined by the method of amino acid ratio coefficient. The results showed that the four different brands were rich in amino acids, complete range, and reasonable proportion of composition. Among them, the content of crude protein and amino acid ratio of Jin Zhu firewood eggs is higher than that of the others, and the evaluation score was up to 82.34. The content of amino acid and the composition of each other are closer to the needs of the human body, and the nutritional value is higher. At the same time, this research showed that firewood eggs have high nutritional value, and have broad prospect in market development and utilization. |
