Solution
Salts and sugars work to preserve foods by creating a hypertonic environment.
Here's the step by step explanation:
-
Salts and sugars are both solutes. When they are added to food, they bind to the water molecules present in the food, reducing the amount of water available for microorganisms.
-
This creates a hypertonic environment. In a hypertonic solution, the concentration of solutes (in this case, salt or sugar) is higher outside the cell (in the food) than inside the cell (of the microorganism).
-
Microorganisms, like bacteria and fungi, need water to grow and reproduce. In a hypertonic environment, water moves out of the cells of the microorganisms, in an attempt to balance the concentration of solutes inside and outside the cell. This process is called osmosis.
-
The loss of water causes the cells of the microorganisms to shrink, which inhibits their growth and reproduction. This is how salts and sugars preserve food.
