In the thesis we were determining biogenic amines and gamma-aminobutyric acid (GABA) contents in 28 samples of dry fermented sausages present in the slovenian market. In the second part of the thesis we analyzed the influence of temperature (5 °C, 15 °C and 25 °C) and storage time (7, 30 and 90 days) of dry fermented sausages on biogenic amines and GABA contents. In reference to the average amount of sausage consumed in Slovenia we determined that safe amount of biogenic amines in dry fermented sausages should be between 120 and 500 mg/kg and that a concentration of 1000 mg/kg causes acute toxicity. In 38 % of analyzed samples we determined histamine in concentration of 1000 mg/kg, of which presents a risk, while another 38 % of the samples had less than 100 mg/kg of it. Largest amount of tyramine was determined in the wild boar sausage sample (3659,80 mg/kg), 63 % of all samples contained less than 100 mg/kg of tyramine. The quick fermentation sausage samples contained below average levels of histamine, tryptamine, tyramine and putrescine. In the second experiment we concluded that time has a negative effect on formation of biogenic amines, their concentration rose with storage time but only until the 30th day. Between the 30th and 90th day concentration actually dropped. Temperature had a big influence on concentrations of putrescine, tyramine and to a slightly lesser degree on histamine and GABA. Lower temperature resulted in lower concentrations of the mentioned biogenic amines.
