| Outline of Final Research Achievements |
High performance liquid chromatographic method by using fluorescence detector was investigated for the simultaneous determination of nonvolatile amines (histamine, cadaverine, putrescine, tyramine and phenethylamine) in fish and its products. Nonvolatile amines were extracted with 5% trichloroacetic acid, and cleaned up with mixed-mode (ion-exchange and reversed-phase) mini-cartridge column. Survey of these five nonvolatile amines content in commercial 22 samples was conducted. Nonvolatile amines were detected in six of fish product samples, and its ranges were 5-678 mg/kg. Nonvolatile amines formation and decomposition in stored fishes were researched. Raw fish samples (tuna, yellowtail and porgy) were stored at the temperature of 25℃ for 3days．Rapid and high levels formation of histamine was observed in yellowtail.
