All measurements were repeated in triplicates and microbial
counts were transformed into logarithms of the number of
CFU (log10 CFU/g). Data were subjected to analysis of variance
(ANOVA) of the Statistical Analysis System software
of SAS Institute using the General Linear Models procedure
(SAS, 1990). Differences among the mean values of different
treatments and storage times were achieved by the least significant
difference (LSD) test. The significance was defined at
