Question

Which of the following scientists discovered the “Pasteurization method of preserving milk”?
A) Louis Pasteur
B) Robert Brown
C) Archimedes
D) None of the above

Answer 1

Hint: The process of pasteurization is named after the person who discovered it. He was a French microbiologist. Pasteurisation is a process in which packaged and non-packaged foods (such as milk and fruit juice) are treated with mild heat.

Complete step by step solution: First, Let’s discuss the pasteurization method of preserving milk.
Pasteurization of milk is the process includes heating raw milk for a particular time at a certain temperature to kill the pathogens found in raw milk. Different kinds of pathogens like bacteria and viruses can be found in raw milk, so it is very important to pasteurize milk before serving the society. Thus, there is a law that milk which is sold to the public has to be pasteurized and packaged in a dairy plant which has a license.

Now, let us take a look into the person who discovered this process. Louis Pasteur was a French microbiologist. Pasteur researched the fermentation process and it led him to the discovery of yeast in alcohol. He learnt that this microorganism was responsible for the fermentation process. Later he discovered that heating wine would kill the microbes which would spoil it. He was able to determine the exact time and temperature that would kill pathogens and it was patented and called Pasteurization. Pasteurization of milk came into practice in the late 1800 as a measure to control the spread of tuberculosis.

Final Answer is: (A) Louis Pasteur.

Note: Pasteurization process is employed not only for preserving milk, but also for other packaged and non-packaged food materials as a measure to ensure safety as well as quality. This also increases the shelf life of food products.
