Sun-drying is a very common method of preservation. Here moisture content of the food is removed using heat from the sun. Using dry salt is also a very common method of preservation of food. Due to salt, the moisture content in food is reduced. Canning is another method of food preservation where food is packed in air tight cans. This method is very common for seafood. Nitrogenation is not a method of food preservation.
