Question

What happens when milk is pasteurized?

(a) Reduces the bacterial population

(b) Destroys spores

(c) Impart color

(d) Impart flavor

I got this question in an online interview.

This is a very interesting question from Process Engineering Applications in section Process Engineering Applications in Food Industry of Food Processing Unit Operations

Answer 1

The correct answer is (a) Reduces the bacterial population

Easy explanation: Pasteurization is not similar to sterilization. Pasteurization reduces the bacterial population of a liquid and destroys the organisms that may cause spoilage and human disease. Spores are not affected by the pasteurization process.
