The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Pasteurization**: Pasteurization is a heat treatment process used to kill pathogens in food and beverages, particularly in milk and juices. This process helps in extending the shelf life of these products and ensuring they are safe for consumption. 2. **Historical Context**: The process is named after Louis Pasteur, who developed this method to prevent spoilage and improve food safety. 3. **Identifying the Correct Temperature and Time**: The question provides several options regarding the temperature and duration for pasteurization. The key points to remember are: - Pasteurization typically involves heating milk at specific temperatures for a set duration. - Commonly accepted conditions for pasteurization include heating milk to 62 degrees Celsius for 30 minutes or to 72 degrees Celsius for 16 seconds. 4. **Evaluating the Options**: - Option A: 30 degrees for 60 minutes - This is too low a temperature for effective pasteurization. - Option B: 40 degrees for 30 minutes - This is also too low for effective pasteurization. - Option C: 62 degrees for 30 minutes - This matches one of the accepted pasteurization conditions. - Option D: 30 degrees for 20 minutes - Again, this is too low a temperature. 5. **Conclusion**: Based on the evaluation, the correct answer is **Option C: 62 degrees for 30 minutes**. ---
