Pasteurization is heating at

Options

A. `70^(@)C` and 60 minutes
B. `80^(@)C` and 30 minutes
C. `120^(@)C` and 60 minutes
D. `60-70^(@)C` and 30 minutes

Answer

To answer the question "Pasteurization is heating at," we will analyze the provided options step by step.

### Step-by-Step Solution:

1. **Understanding Pasteurization**:
- Pasteurization is a process of heating food and beverages to a specific temperature for a certain period to kill harmful microorganisms and extend shelf life.

2. **Identifying the Temperature Range**:
- Pasteurization typically involves heating at temperatures below 100 degrees Celsius. The common temperature range for pasteurization is between 60 to 70 degrees Celsius.

3. **Evaluating the Options**:
- **Option A**: 70 degrees Celsius in 60 minutes - This is too high and too long for standard pasteurization.
- **Option B**: 80 degrees Celsius in 30 minutes - This temperature is above the typical range for pasteurization.
- **Option C**: 20 degrees Celsius in 60 minutes - This is not a heating process and is too low for pasteurization.
- **Option D**: 60 to 70 degrees Celsius in 30 minutes - This option falls within the acceptable range for pasteurization.

4. **Conclusion**:
- The correct answer is **60 to 70 degrees Celsius in 30 minutes**, as it aligns with the standard pasteurization process.

### Final Answer:
Pasteurization is heating at **60 to 70 degrees Celsius in 30 minutes**.
