The evolution of free amino acids and biogenic amines during 23 days of drying and ripening was determined in the traditional, dry-fermented sausage, Sjenički sudžuk . The concentration of most amino acids increased significantly ( P < 0.05) over time, giving rise to a final concentration of total free amino acids of 600 mg/100g dry matter. Thus, the chief precursors became available for indigenous aminogenic microbiota, enabling formation and accumulation of biogenic amines. Total biogenic amines reached the level of 399 mg/kg by day 23 of processing. Putrescine and tyramine were the predominant amines. Their concentrations increased significantly ( P < 0.05) during processing, ranging from 91.9 to 212 mg/kg and from 48.5 to 147 mg/kg, respectively. A positive outcome of this study is the very low registered concentration of histamine (9.69 mg/kg), the most important amine both from the toxicological and hygienic points of view.
