What are the significance of osmosis to food preservation methods such as salting and drying?
Salting, sugar-curing, &c. apply osmosis in that both of these compounds are hygroscopic and thus draw water out of the food to be preserved over the semi-permeable surface of the food, from one solution into another, thus making the environment inhospitable for most bacteria and mold.
Simple air drying works in the same way, but osmosis is not a factor; evaporation is.

What are the basic principles of salting?
The basic principles of salting involve the use of salt to preserve food by inhibiting the growth of bacteria and mold. Salt draws moisture out of food through osmosis, creating an environment that is less hospitable to microorganisms. Additionally, it enhances flavor and can improve texture. Salting can be done through dry methods, where salt is applied directly, or wet methods, where food is submerged in a brine solution.
How is osmosis realted to salting food?
Osmosis is the process where water moves across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. When salt is applied to food, it creates a higher concentration of solute outside the food cells, causing water to move out of the cells through osmosis. This can lead to dehydration of the food, enhancing flavor and preservation by inhibiting bacterial growth. Thus, salting food effectively draws out moisture while adding taste.
