How long does HHST Pasteurization last at 0.5 seconds?

1. 1 second

2. 0.5 seconds

3. 5 seconds

4. 10 seconds

The correct answer is: 0.5 seconds

The duration of HHST (High-Temperature Short Time) Pasteurization at 0.5 seconds indicates that the process is designed to effectively pasteurize the milk or dairy product in half a second. This method is specialized for maintaining the quality of the product while ensuring that pathogenic microorganisms are eliminated. In this context, the specific mention of "0.5 seconds" refers directly to the pasteurization time itself, which means that the correct understanding of the question confirms that the pasteurization process is executed for that exact duration. This method is efficient and suited for the rapid treatment of liquid products, aiming to retain their sensory and nutritional qualities while ensuring safety. The other durations mentioned do not apply in this context, as they do not reflect the intended timing of the pasteurization process being evaluated. Thus, the reasoning aligns precisely with the definition and goal of HHST pasteurization.
