Question

Which of the following causes osmosis in food items?

• A. Oil
• B. Vinegar
• C. Heat treatment
• D. Salt

Answer 1

The correct option is D Salt

Food can be preserved by different methods. Salting is one of the oldest methods which is used for the preserving food for a long time. The food is soaked in salt or brine water. The addition of salt removes the moisture by the process of exosmosis. Due to the difference in the concentration inside and outside of the cell, the water is removed from the food. The presence of salt and no moisture prevents bacterial contamination. So, the food does not get degraded for a longer period of time.

Thus, the correct answer is option D.
