| Abstract: | Taurine in foodstuff is determined by fluorophotometry. The RSD of the determination is found to be smaller than 4.4%. Recoveries in the range of 92.0%~102% were found by the standard addition method. Interferences from other aminoacids were avoided by the pretreatment of the sample. The method reported was proved to be good in selectivity and convenient in operation, and is suitable to be used in the analysis of foodstuffs. |
