Answer 2

Answer:

The correct answer is natural.

Explanation:

• Due to the fact that salt lowers the water activity of foods, it is useful as a preservative.
• The amount of unbound water that is available for microbial growth and chemical reactions is known as a food's water activity. The capacity of sodium and chloride ions to bind with water molecules is thought to be the reason salt can reduce water activity.
• Salting food can also cause microbial cells to go through osmotic shock, which causes the cell to lose water and ultimately leads to cell death or slowed growth.
