Antimicrobial activity of proccesed spices used in traditional southern italian sausage processing

Abstract

Several spices are used to process 'Nduja, a traditional Calabrian sausage, well knownfor its typical flavor and piquancy. Despite wide use of spices for meat curing andcontrolling undesired microorganisms, no studies reported antimicrobial effectivenessof the spices in the 'Nduja processing. The aim of this work was to evaluate theantimicrobial activities against 10 foodborne pathogens of processed spices used inthe 'Nduja industrial manufacturing. Spice extracts (using ethanol, methanol andwater as solvents) were investigated by disk diffusion assay for their antimicrobialactivity. Methanol extracts showed the best results, mainly against Bacillus cereusstrains. Thus, they were further evaluated, through microdilution automated spectrofluorimetricabsorbance readings. Many spice methanol extracts showed low antimicrobialactivities, although B. cereus strains were still more sensitive. In addition, twoout of the three spice mixtures showed medium and high inhibition activity againstEscherichia coli ATCC 35401 and Yersinia enterocolitica DSM 4780, respectively.
