This study aimed to examine the content of biogenic amines (BAs) throughout the manufacture of lakerda. The effect of different ripening temperatures (+4, 15 and 20C) on BAs formations during producing of lakerda, as well as the relationship between productions of BAs and chemical properties (pH, salt content, a(w) and WPS) were also studied. Tyramine, spermine and phenylethylamine were the major BAs in fresh and all stages of production, respectively. During ripening, all BAs, except for spermine, decreased significantly (P<0.05) in all temperature conditions. Surprisingly, the use of elevated temperatures (15 and 20C) for ripening significantly (P<0.05) decreased the amines contents. In the final products, total BAs ranged from 63.93 mg/kg in the sample ripened at 15C to 68.79 mg/kg in the sample ripened at 20C. Basic chemical parameters were significantly correlated with BAs. Traditionally production of lakerda is suitable from the toxicological point of view.
