Question

how does osmosis help in food preservation?​

Answer 1

Answer:

The principle of osmosis is used to pre-serve jams, jellies and pickles. In this process, water tends to draw out from microbes (plasmolysis) and makes it dehy-drated, thus killing them. ... Hence, preserved foods like pickles tend to spoil if not stored properly.

Explanation:

An additional method that can be considered as osmosis is drying. During the drying period, whether by solar heat, a fire or a machine, the water inside cells passes eventually on to the surface of the food where an equilibrium is established between water from the food and local atmospheric humidity. When the food can no longer emit water vapor, osmosis ceases and the now dried food is stored.
