Question

Pasteurized milk can be consumed without boiling why?
A) As it is free from enzymes
B) As it is free from microbes
C) As it is free from preservatives
D) Both A and B

Answer 1

Hint: A process of removing pathogens by the means of short heating.

Complete step-by-step answer:
Pasteurized milk does not contain any enzymes or microbes so they do not require to undergo boiling. This is because, during the pasteurization, the milk has already undergone boiling.

Additional information
-Pasteurization is the process of treating food items with heat, mostly around 100° C or less.
-This process deactivates the enzymes, organisms like bacteria, etc., which has a risk of disease and results in the spoilage of food.
-Milk is pasteurized due to its ability to act as a medium for the growth of microbes.
-When the milk is kept for some time at a particular temperature, the pathogens start to grow resulting in the most dangerous and poisonous food.
-Pasteurization kills these bacteria and prevents microbial growth on any product.
-The milk undergoes high temperature only for a short period and then undergoes cooling, increasing the shelf life of the milk.
So, the correct answer is ‘Both A and B'.

Note: Since 1117 AD, the process of heating the wine to preserve them for long has been practiced in China. It was later developed in 1864 by a French chemist Louis Pasteur in Arbois, and the technique was named after him. It is now used widely in the Dairy industry and in preserving food.
