Question

Arrange the following steps in correct sequence during commercial canning of foods:
A. Exhausting
B. Filling
C. Sealing
D. Thermal processing
E. Cooling
Choose the correct answer from the options given below:

• A. B, A, C, D, E
• B. B, A, D, C, E
• C. B, A, C, E, D
• D. B, A, E, C, D

Hint:

Canning: Fill → Remove air → Seal → Heat → Cool.

Answer 1

The Correct Option is A

Concept: Commercial canning is a preservation technique involving sealing food in containers and applying heat to destroy microorganisms.

Step 1: Filling (B).
Food is first:
• Placed into containers

Step 2: Exhausting (A).
Then:
• Air is removed from the container
• Prevents oxidation and swelling

Step 3: Sealing (C).
Next:
• Containers are hermetically sealed

Step 4: Thermal processing (D).
After sealing:
• Heat treatment destroys microorganisms
• Ensures safety and shelf life

Step 5: Cooling (E).
Finally:
• Rapid cooling prevents overcooking
• Maintains quality

Step 6: Final sequence. \[ B \rightarrow A \rightarrow C \rightarrow D \rightarrow E \] Final Conclusion:
Option (1) is correct.
