Abstract

The effect of mixed starter cultures on biogenic amine production was examined during the ripening process of dry camel meat sausage. Changes in pH, moisture content, proteolysis, microbial counts and lipid oxidation were also studied. The combination of three amine-negative bacteria, resulted in a drastic reduction of biogenic amine production. The highest total free amino acid concentration was observed in batches manufactured with mixed starter cultures. The bactericidal properties of L. sakei improved the hygienic quality of sausages by decreasing the number of Enterobacteriaceae. Inoculation of sausages with a mixture of strains, significantly delayed lipid oxidation and enhanced sensory characteristics.
