[Biogenic amines in food: effects of histamine, tyramine and phenylethylamine in the human].

The effect of 25 mg histamine, 25 mg tyramine and 5 mg phenylethylamine resp. in apple juice on 27 healthy volunteers was studied using a randomized placebo-controlled double-blind procedure. No statistically significant effect was found with histamine and tyramine, but phenylethylamine produced symptoms like headache, dizziness and discomfort in some volunteers. In a second experiment the effect of four different wines (2 dl) containing naturally several biogenic amines in various amounts (histamine n.d. - 21 ppm; tyramine 1-23 ppm; phenylethylamine n.d. - 6 ppm; putrescine 2-55 ppm) on 20 volunteers was recorded. The percentage of volunteers experiencing symptoms was of the same order of magnitude as in the first experiment. No correlation was found to exist in this second experiment between the occurrence of symptoms and the concentration of biogenic amines in the wine samples.
