Explain why pasteurized milk can be consumed without boiling.

Explanation

### Step-by-Step Solution:

1. **Definition of Pasteurization**: Pasteurization is a process developed by scientist Louis Pasteur. It involves heating milk to a specific temperature to kill harmful microorganisms.

2. **Process of Pasteurization**: During pasteurization, milk is heated to about 70 degrees Celsius for a duration of 15 to 30 minutes. This heating effectively kills or inactivates harmful bacteria present in the milk.

3. **Cooling and Storage**: After the heating process, the milk is rapidly chilled to prevent the growth of any remaining bacteria. This rapid cooling helps in preserving the quality and safety of the milk.
