Question

Which of the following is the reason for the preservation of food by boiling?

• A. High temperature kills the bacteria by denaturing the proteins
• B. It stops the chemical reaction
• C. It changes the colour of the food
• D. All of the above

Answer 1

The correct option is A High temperature kills the bacteria by denaturing the proteins

Option A is correct.
At high-temperature bacteria present in the food are killed. Also, it will not affect the quality of minerals present in the food.

But, there must be some temperature, like here more than ${100}^{\circ }c$ is required to kill the bacteria.

So, this method is mainly adopted everywhere. (i.e. Boiling)
