Question

Given below are two statements:
Statement (I): The rate of heat transfer to the thermal centre of a container depends on the size of container, but not the shape
Statement (II): The rate of heat transfer to the thermal centre of can is improved by agitating the container
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are true
• B. Both Statement (I) and Statement (II) are false
• C. Statement (I) is true but Statement (II) is false
• D. Statement (I) is false but Statement (II) is true

Hint:

To optimize retort processing in dairy canning:
- Use containers with high surface area-to-volume ratios (slender shapes) to minimize heat transfer distances.
- Use rotary/agitating retorts to induce convective heating, shortening sterilization times and preserving product color and flavor.

Answer 1

The Correct Option is D
