The objective of this study was to investigate the levels of bioactive amines in soy sauce. A method for the extraction of amines was optimized and an ion pair-HPLC method was validated. Overall, tyramine was the prevalent amine, followed by putrescine, histamine, phenylethylamine and cadaverine. The concentrations of amines varied widely among samples. The brands could be divided into two groups. The first one contained three amines; there was prevalence of cadaverine followed by tyramine and putrescine; and total amine levels were low. The second group contained four amines; there was prevalence of tyramine followed by histamine, phenylethylamine and putrescine; and total amine levels were high. A brand with lower NaCl levels contained significantly higher amine levels. Based on the levels of amines detected, a high percentage of samples could cause adverse effects to human health.

D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000588 Amines A group of compounds derived from ammonia by substituting organic radicals for the hydrogens. (From Grant & Hackh's Chemical Dictionary, 5th ed) Amine
D001679 Biogenic Amines A group of naturally occurring amines derived by enzymatic decarboxylation of the natural amino acids. Many have powerful physiological effects (e.g., histamine, serotonin, epinephrine, tyramine). Those derived from aromatic amino acids, and also their synthetic analogs (e.g., amphetamine), are of use in pharmacology. Amines, Biogenic,Biogenic Amine,Amine, Biogenic
D015203 Reproducibility of Results The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.
