Which of the following is true regarding pasteurization of milk? (AIPG 10)
|A||Bacterial count is reduced by 90%|
|B||Kills all bacteria and spores|
|C||Kills all bacteria and no spores|
|D||Kills all bacteria except thermoduric bacteria|
Pasteurization of milk is 'heating of milk to such temperature and for such period of time as is required to destroy any pathogens that may be present while causing minimal changes in the composition, flavor and nutritive value.
Pasteurization kills about 90% of the bacteria in the milk including the most heat-resistant tubercle bacillus and the Q-fever organisms. Pasteurization does not kill thermoduric bacteria not the bacterial spores.
