Correct option is C

The correct answer is: (c) To kill harmful microorganisms
Explanation
  • Pasteurisation is a heat treatment process used mainly for milk and other liquids, where the liquid is heated to a specific temperature for a short time and then quickly cooled.
  • This process kills harmful bacteria and pathogens without significantly affecting taste or nutritional value.
Information Booster:
  • Named after Louis Pasteur, who developed the method in the 19th century.

  • Commonly used in milk, juice, and dairy products.

  • Helps extend shelf life by reducing microbial load.

  • Standard milk pasteurisation is done at 72°C for 15 seconds (HTST method).

  • It does not sterilise the food but makes it safe for consumption.​
