Question

Explain the biological principle involved in the storage of jams and pickles by adding excess sugar and salt, respectively.

Answer 1

• The addition of excess sugar and salt to jams and pickles leads to an increased concentration of the solution in them i.e., the solution is hypertonic.
• Whenever the microorganism enters the pickle or jam it leads to exosmosis as the concentration of cell sap of microorganism is lower compared to surrounding.
