Abstract

In order to reveal the existing forms and levels of biogenic amines in commercial sufu in China, the biogenic amine contents in 20 commercial brands of white sufu and red sufu sold in China were analyzed by dansulfonyl chloride pre-column derivations combined with HPLC. The results showed that the main biogenic amines in sufu were tyramine, histamine, putrescine, tryptamine, β-phenethylamine and cadaverine, with average contents of 73.7 mg/kg, 43.7 mg/kg, 38.5 mg/kg, 27.7 mg/kg, 5.4 mg/kg and 5.4 mg/kg, respectively. The content of each biogenic amine in white sufu was significantly higher than that in red sufu (P<0.05). The average contents of tyramine, histamine, putrescine, tryptamine, β-phenethylamine and cadaverine in white sufu were 1.6, 1.9, 3.4, 3.3, 2.3 and 3.0 times that of in red sufu, respectively. In addition, the level of each biogenic amine in the same type of different brands of sufu showed high differences.
