cooking.

Ungerminated legume seeds (broad bean, chick pea and lupine) were contained all
tested biogenic amines. Tryptamine (TRY) was the main biogenic amine detected,
and its concentration considerably increased during the germination. beta-Phenylethylamine
(PHE) was detected in small amounts and its concentration slowly increased
during germination. The concentration of tyramine (TYR) showed a fluctuation
pattern of changes during germination in all tested legumes. The concentrations
of cadaverine (CAD) and putrescine (PUT) increased during the germination period
in all tested grains. However, histamine (HIS) showed a fluctuated pattern of
changes in both broad bean and lupine, and a gradual increase in chick pea.
Spermidine (SPD) and spermine (SPM) contents of broad bean and chick pea showed
a fluctuation pattern of change, while, a decrement trend of change was recorded
for lupine along the germination period. By cooking, legume samples became free
of biogenic amines which appeared in the boiling water. Heat treatment seems to
have little effect on the concentration of biogenic amines in legume sprouts.
The amounts of biogenic amines detected in the boiling water are less than the
initial amounts of the sprouts (expected amounts).
