What is the duration for heating milk at 72 degrees celsius in the pasteurization technique?

Options

A. Sixty seconds
B. Ninety seconds
C. Fifteen seconds
D. Forty-two seconds

Answer

**Step-by-Step Solution:**

1. **Understanding Pasteurization**: Pasteurization is a technique used to kill harmful microorganisms in food and beverages, particularly milk. It was developed by Louis Pasteur.

2. **Purpose of Pasteurization**: The main goal of pasteurization is to make milk safe for consumption by reducing the number of pathogens and spoilage organisms without significantly affecting the nutritional quality of the milk.

3. **Heating Process**: In the pasteurization process, milk is heated to a specific temperature for a certain duration. This ensures that all parts of the milk reach the required temperature to effectively kill harmful microorganisms.

4. **Specific Temperature and Duration**: The question asks about the duration for heating milk at 72 degrees Celsius. The correct duration for this temperature in the pasteurization process is 15 seconds.

5. **Conclusion**: Therefore, when milk is heated to 72 degrees Celsius, it should be held at that temperature for **15 seconds** to ensure it is pasteurized effectively.

**Final Answer**: The duration for heating milk at 72 degrees Celsius in the pasteurization technique is **15 seconds**.
