Temperature in deep freezes for preserving food articles is

Options

A. `0^(@)C`
B. `-4^(@)C`
C. `-10^(@)C`
D. `-18^(@)C`

Answer

**Step-by-Step Solution:**

1. **Understanding the Purpose of Deep Freezing:**
- Deep freezers are used to preserve food by maintaining a very low temperature. This low temperature is crucial for preventing spoilage.

2. **Effect of Low Temperature on Enzymes:**
- At low temperatures, the activity of enzymes, particularly those produced by bacteria and fungi, is significantly reduced. Enzymes are proteins that catalyze biochemical reactions, including those that lead to food spoilage.

3. **Temperature Range of Deep Freezers:**
- Most household deep freezers operate at temperatures ranging from -23°C to -18°C. This range is effective in slowing down or halting the enzymatic activity that can lead to food spoilage.

4. **Conclusion:**
- Therefore, the temperature in deep freezers for preserving food articles is typically between -23°C and -18°C.

5. **Final Answer:**
- The correct answer is that the temperature in deep freezers for preserving food articles is between -23°C and -18°C.
