Similarly, lactic acid bacteria presented a difference (p b 0.0001) for
treatment effect in contrast 1. However, no significant difference
(p N 0.05) between irradiated samples throughout storage was found.
Considering the time of storage, there was a significant effect (p =
0.0019), with microbial growth for all treatments between zero and
28 days. Also, the mesophilic anaerobic, limit of 107 CFU·g−1 was not
reached. For anaerobic psychotropics, contrast 1 presented a significant
difference (p b 0.0001) between control and irradiated samples. Contrast
2 was also significant (p = 0.0262). Moreover, there was a
significant effect of time (p b 0.0001) as counts increased over time.
