Question

At which temperature is frozen storage generally operated?

• A. \(\text{\(-0^\circ C\)}\)
• B. \(\text{\(-18^\circ C\)}\)
• C. \(\text{\(-50^\circ C\)}\)
• D. \(\text{\(-60^\circ C\)}\)

Hint:

Frozen food storage is typically maintained at \(-18^\circ C\) to prevent microbial growth and maintain food quality.

Answer 1

The Correct Option is B

Step 1: Understanding frozen storage temperatures.
- The standard temperature for frozen storage is \(-18^\circ C\), which is cold enough to prevent microbial growth and preserve food quality.
Step 2: Explanation of incorrect options.
- \(-0^\circ C\) (A): This is not low enough for frozen storage.
- \(-50^\circ C\) and \(-60^\circ C\) (C and D): These temperatures are used for specialized cryogenic storage, not for standard frozen food storage.
Step 3: Selecting the correct option. Since \(-18^\circ C\) is the commonly accepted temperature for frozen storage, the correct answer is (B) \(-18^\circ C\).
