Drying is a method of food preservation that works by removing water, which is required for decay and the growth of microorganisms. Water is usually removed by evaporation (air drying, sun drying, smoking or wind drying) but, in the case of freeze-drying, food is first frozen and then water is removed by sublimation.
There are many different modes of drying and these include drying on a bed dryer, a fluidized bed dryer as well as an enclosed shelf dryer. They all have their own advantages for particular applications.
Many different foods are prepared by drying, including Parma ham, bresaola, beef jerky, and fruits that normally have a high water content, such as prunes, raisins, figs, and dates.
Dried and salted reindeer meat is a traditional Lappish food. First the meat is soused. It is kept in saltwater for a couple of days
to guarantee the conservation of the meat.
Then the meat is dried in the sun in spring when the air temperature is
below zero. The dried meat can be further processed to make
soup.
