[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.
