Table 1.
Microbial loads (log CFU/g) of yeasts and molds, total psychrotrophic anaerobic and aerobic populations, Enterobacteriaceae. The values shown are the mean value of all the samples analyzed for each product type (±standard deviation). Different letters in column indicate significantly different values between the different product types, as determined by paired t-tests (p < 0.05).
