The process of ________ is used to increase the shelf life of milk by destroying disease-causing microorganisms.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. pasteurisation.
The process of pasteurization is used to increase the shelf life of milk by destroying disease-causing microorganisms. In this process, milk is heated to a specific temperature (usually around 72°C to 75°C) for a short period, then rapidly cooled. This technique kills harmful bacteria such as E. coli, Salmonella, and Listeria without significantly affecting the milk's nutritional content. Pasteurization ensures that milk is safe for consumption and extends its shelf life by reducing microbial spoilage, thereby maintaining its quality and freshness for longer periods.
