The consumption of fermented goods has been related with outbreaks of foods intoxications, like these biogenic amines have been associated to the consummations of these products. The aims went to assess the potential of amines formation in dry fermented sausage added or not with starter and fiber, determination of amines formation in cooked salami added or not with organic acids. The dry fermented sausages were fabricated and cased in artificial collagen no eatable gut then, ripening under controlled conditions of temperature, moisture and air stream. The cooked salamis were added with organic acids (lactic and citric), cased in artificial collagen no eatable gut and cooked. The products were according to the microbiologic available legal patterns. The histamine reached amounts of 145,61; 93,38 and 130,10 mg·kg-1 and the tyramine reached amounts of 67,05; 70,28 and 71,87 mg·kg-1 for the dry fermented sausages treatments: control, starter and starter and fiber respectively. The histamine in the cooked salami treatments: control, lactic acid and citric acid reached amounts of 48,06; 55,37 and 49,16 mg·kg-1 and the tyramine reached amounts of 11,00; 11,06 and 11,35 mg·kg-1 respectively. There were no differences at the level tested (p<0,05). In conclude the starter did not avoid the amine formation, attributed to the polluting bacterium found already in the raw materials. The temperature and the organic acids did not influence in the final amounts of amines in the cooked salami. The taste assess was not influenced by the presence of amines. The addition of glucose and sucrose avoided larger amines amounts in the fermented salami and the wheat fiber did not interfere in the metabolism of the microorganisms.
