Question

is the process of heating milk followed by sudden cooling before storage.

• A. Drying
• B. Salting
• C. Pasteurisation

Answer 1

The correct option is C Pasteurisation

Milk is heated to about ${70}^{0}C$ for 15 to 30 seconds and then quickly cooled to ${10}^{0}C$ before storage. This sudden cooling kills all the microbes in the milk. This process was discovered by Louis Pasteur and is called pasteurisation.
