Answer 2

Answer:

Milk sold in packets can be stored for 2 or 3 days as it was packed after the process of pasteurisation.

Pasteurisation is one type of food preservation method. Pasteurisation is the process developed by Louis Pasteur, especially to store milk. In pasteurisation, milk is first heated to about 70 degrees Celsius for 15 to 30 seconds. Then it is suddenly chilled and stored. This prevents the growth of microbes. Pasteurisation deactivates the microbes and reduces the enzyme activity by reduction of temperature.
