In frankfurters immersed in AM5® (liquid smoke), counts of
L. monocytogenes on the 8th day of storage at 8 C (Fig. 3) were 3 log
lower than in non-treated controls. The presence of sodium lactate(Purasal S®) enhanced the antimicrobial activity of AM5®, and at
the 28th day at 8 C, the counts were 2 log lower than in the
frankfurters treated with only one antimicrobial or in the nontreated
controls.
