Question

All pathogenic types of bacteria and nearly all other objectionable organisms in milk are killed by:

• A. Thawing
• B. Pasteurization
• C. Cooling
• D. Blending

Hint:

Pasteurization = heating milk to kill germs, then cooling it fast.

Answer 1

The Correct Option is B

Pasteurization is the process used to make milk safe for consumption by killing harmful microorganisms.
In this process, milk is heated to a specific temperature and held there for a set time, then cooled rapidly.
This destroys pathogenic bacteria such as tuberculosis bacteria, E. coli, and other objectionable organisms.
Thawing is simply warming frozen food and does not kill bacteria.
Cooling only slows down bacterial growth but does not kill them.
Blending is mixing and has no effect on bacteria.
Therefore, pasteurization is the correct and standard method for making milk safe.
