Question

Consider the following statements and identify the correct statements on freezing of foods:
A. Rapid freezing forms small ice crystals
B. Slow freezing damages cell structure
C. Freezing stops enzymatic activity completely
D. Latent heat is removed during freezing
E. Freezing improves microbial growth
Choose the correct answer from the options given below:

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

Hint:

Fast freezing = better quality due to small ice crystals.

Answer 1

The Correct Option is C

Concept: Freezing is a preservation method that reduces temperature to slow down microbial growth and enzymatic activity.

Step 1: Evaluating Statement A.
Rapid freezing:
• Produces small ice crystals
• Causes less damage to tissues Correct.

Step 2: Evaluating Statement B.
Slow freezing:
• Produces large ice crystals
• Ruptures cell walls Correct.

Step 3: Evaluating Statement C.
Freezing:
• Slows enzymatic activity
• Does not completely stop it Thus, incorrect.

Step 4: Evaluating Statement D.
During freezing:
• Latent heat of fusion is removed Correct.

Step 5: Evaluating Statement E.
Freezing:
• Inhibits microbial growth
• Does not improve it Thus, incorrect.

Step 6: Final selection. \[ A, B, D \] Final Conclusion:
Option (3) is correct.
