Question

Is vacuum-packed food safe from the growth of bacteria? Yes, because the vacuum always destroys the bacteria Yes, because all bacteria need oxygen to grow No, because bacteria can grow without bacteria No, because the vacuum increases the food's water activity

Answer 1

The correct answer is: No, because the vacuum increases the food's water activity.Vacuum packaging can actually create an environment that is conducive to bacterial growth. When food is vacuum-packed, the removal of air creates a low-oxygen environment. While some bacteria do require oxygen to grow, many do not and can thrive in such conditions. Additionally, the vacuum can increase the water activity in the food, which can also promote bacterial growth. Therefore, vacuum-packed food is not necessarily safe from the growth of bacteria.
