Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary preservation mechanism?Reduction of water activity through osmotic dehydration of microorganisms
2. What is the scientific principle involved?Osmosis, leading to microbial plasmolysis and inactivation
3. What does salt do to keep food from going bad?Salt pulls water out of food and the germs on it, making it hard for bacteria to grow.
4. How does salting help make food taste better?Salt changes the proteins and fats in foods, giving cured meats a tasty flavor and a softer texture.

Water Activity (aw): The amount of unbound water available in a food for microbial growth and chemical reactions.
Hypertonic Environment: A solution with a higher solute concentration (like salt) compared to another solution.
Plasmolysis: The process in plant and animal cells where the cytoplasm shrinks away from the cell wall due to water loss.
