Pasteurization is the process used to what in milk?

• A. It kills pathogenic microorganisms in milk
• B. It sterilizes milk completely
• C. It increases fat content
• D. It is the same as UHT

Answer: (A)

Pasteurization is a heat treatment designed to kill pathogenic microorganisms in milk, making it safer to drink while preserving most of the taste and nutrients. The goal is safety, not total sterilization, so it greatly reduces harmful bacteria but doesn’t eliminate every microbe. Because it’s not a sterilization process, some heat-tolerant spores or nonpathogenic bacteria can remain. It also doesn’t change the fat content, since fat level is determined by the milk itself, not by this heating step. Ultra-high temperature processing (UHT) is a different method that heats milk to much higher temperatures to achieve sterility and shelf-stability, which is why it isn’t the same as pasteurization.
