title: Changes in biogenic amine and polyamine contents in slightly fermented sausages manufactured with and without sugar.
abstract: The effect of sugar omission on biogenic amine contents of slightly fermented sausages during ripening and storage was evaluated. Two batches of spontaneously fermented sausages were produced with and without sugars in two different trials at pilot-plant scale. Ripened sausages were stored at 4 and 19°C for a further 20 days. Tyramine and cadaverine were the main amines formed during ripening, their contents being significantly higher in batches without sugar. High counts of LAB and Enterobacteriaceae could be associated with the production of tyramine and cadaverine, respectively. The occurrence of putrescine depended on the trial and batch. Sausages without sugar contained more putrescine than those with sugar in trial 1, but this was not repeated in trial 2, in which a high production of agmatine occurred. Tryptamine and phenylethylamine were only detected in the later stages of ripening, their contents also being higher in sausages without sugar. Biogenic amine contents generally rose during storage at 19°C, the increase being especially important for cadaverine and tyramine in sausages without sugar. Levels of spermidine and spermine remained constant during ripening and decreased slightly during storage. Sugar omission is not recommended because it might increase biogenic amine accumulation during the manufacture and storage of slightly fermented sausages.
