Adding salt or sugar to foods is a great way to preserve these foods for a longer period of time and prevent bacterial spoilage. Why?ANSWERAdding sugar or salt creates an isotonic environment, and water will be lost from the bacterial cell.Adding sugar or salt creates a hypertonic environment, and water will be lost from bacterial cells, leading to lysis of the cell wall.Adding sugar or salt creates a hypertonic environment, and water will be lost from bacterial cells, leading to plasmolysis.Adding sugar or salt creates a hypotonic environment, and water will be gained by the bacterial cell.
