Question

Salt is used as a common preservative of many household food items. Which of the following is a role of salt in food preservation?

• A. Salt absorbs water from foods, making the environment too dry to prevent harmful mold or bacteria
• B. Salt slows the oxidation of fats
• C. Salt enhances the taste of food
• D. None of the above

Answer 1

The correct option is A Salt absorbs water from foods, making the environment too dry to prevent harmful mold or bacteria

Salt is hygroscopic in nature. It tends to absorb water, so its application on food materials causes absorption of water or moisture, making the environment too dry and unsuitable for harboring or supporting mold or bacterial growth.

So, the correct option is 'salt absorb water from foods, making the environment too dry to support harmful mold or bacteria'.
