The antimicrobial effect of NovaGARD®LM100 and Nova-
GARD®NR100 in the experimentally contaminated bolognas
maintained at 8 C, when compared to those containing Purasal S®
and the controls, is presented in Fig.1. Counts of L. monocytogenes in
the control bolognas increased 5 log in 10 days at 8 C and did not
change until the 30th day. On the 10th and 20th days at 8 C, thecounts in the bolognas formulated with NovaGARD®LM100 were
app 3 log and 2 log lower than in the other three types of bolognas
(p < 0.05), respectively. On the 30th day, a residual 0.5 log difference
was observed. NovaGARD®LM100 was more effective than Nova-
GARD™ NR100 or Purasal S® for inhibiting growth of
L. monocytogenes. The inhibiting capacity of Purasal S® and Nova-
GARD®NR100 did not differ significantly from the control
(p > 0.05).
