Update on Standard Methods for the Examination of Dairy Products, 15th Edition

The microbial content of unexpired pasteurized milk from selected supermarkets in a developing country

“…This is an extremely high coliform count which is greater than the acceptable count of 10 CFU/mL as defined by Standard Methods for the Examination of Dairy Products (SMEDP) in 1993 [12] . This high microbial activity correlates well with the decolourizing time of less than one hour in the methylene blue reduction test.…”

“…According to SMEDP (1993) [12] samples CDa025 (94 000 SPC/mL) and LCr018 (79 000 SPC /mL) were found to have an unacceptable high microbial load. On the basis of comparison with SMEDP, samples SCr017 (1 050 CFU/mL), SID020 (>300 CFU/mL), CDa025 (>300 CFU/mL), LCr017 (30 CFU/mL), BCr016 (13 400 CFU/mL), SIDe020 (>300 CFU/mL) and SID017 (38 CFU/mL) were found to contain an unacceptable number of coliforms.…”

Viability of probiotic micro-organism Lactobacillus acidophilus in dairy chocolate dessert and its action against foodborne pathogens

“…pH determination was performed with digital pH meter (Micronal, B-375) by direct insertion of the electrode in the sample (MARSHALL, 1993). Titratable acidity was determined by the method described by BRASIL (2006) …”

Performance of two ready-to-use systems for enumeration of aerobic mesophilic microorganisms in frozen goat milk

“…Packages were homogenized by manual shaking, disinfected with 70% alcohol, punctured with sterile scissors and 10 mL of the content were transferred to a sterile flask. These samples were submitted to decimal dilutions up to 1:1.000 in sterile phosphate dilution water (14,17).…”
