Determination of Taurine in Food Products by Amino Acid Autoanalyzer

摘要:

本文利用氨基酸自动分析仪测定食品中牛磺酸的含量，建立了氨基酸自动分析仪对食品中牛磺酸的测定方法，并对此方法进行了精密度和准确度的验证实验，该法的相对标准偏差为0.27%，回收率为100.4~102.0%，样品经预处理可防止其他氨基酸的干扰，本法灵敏度高、专一性强，其最低检出限为10 pmol。

Abstract:

This paper introduced a method of determining Taurine in foods by using amino acid auto-analyzer, and verified this method by the precision and accuracy experiment. The relative standard deviation of the method was 0.27 % and the recovery rate ranged from 100.4 % to 102.0 %. Samples should be pretreated to prevent the interference of other amino acids. The method has high sensitivity and strong specificity, the minimum detectable level can reach 10 pmol.
