中文摘要:

      目的 测定广西区内海鸭蛋氨基酸含量及其组成, 分析广西海鸭蛋的品质。方法 采用盐酸水解法处理18组海鸭蛋样品, 通过氨基酸自动分析仪测定16种氨基酸总含量, 分析海鸭蛋各氨基酸的含量及其组成。结果 18份海鸭蛋样品中氨基酸的测定结果表明, 广西海鸭蛋中氨基酸总量在11.99~13.79 g/100 g范围, 各氨基酸占氨基酸总量的比值相近, 其中谷氨酸的含量最高, 约占氨基酸总量的13%, 组氨酸含量最低, 约占氨基酸总量的2%, 其他氨基酸的含量均在3%~9%的范围内。结论 广西海鸭蛋氨基酸总含量有差异, 但氨基酸组成较稳定, 各氨基酸占氨基酸总量的比值相近, 谷氨酸的含量最高, 组氨酸含量最低。

英文摘要:

      Objective To determine the amino acid content and composition of sea duck eggs in Guangxi, and analyze the quality of sea duck eggs. Methods Totally 18 groups of sea duck egg samples were processed by hydrochloric acid hydrolysis, and the total content of 16 amino acids was determined by the automatic amino acid analyzer, and the content and composition of each amino acid in sea duck eggs were analyzed. Results The determination results of amino acids in 18 sea duck egg samples showed that the total amount of amino acids in sea duck egg in Guangxi ranged from 11.99 to 13.79 g/100 g, the ratio of each amino acid content to the total amount of amino acids were similar. Among them, the content of glutamic acid was the highest, accounting for about 13% of the total amino acids, while the content of histidine was the lowest, accounting for about 2% of the total amino acids, and the contents of other amino acids were in the range of 3%?9%. Conclusion The total amino acid content of sea duck eggs in Guangxi is different, but the amino acid composition is stable, and the ratio of each amino acid to the total amino acid is similar, with the highest content of glutamic acid and the lowest content of histidine.
