Food preservation methods are necessary to protect harvests of food crops from spoilage due to fungal or bacterial colonization and/or insect and rodent infestation.
Contents
Methods
Main methods of food preservation are
- desiccation through drying or through osmotic pressure across the cell walls of microbes through salting, and candying (or preserving in syrup).
Drying
Drying is one of the most common methods of food preservation in use today. One of the primary advantages of cereal grains, oil seeds, nuts and pulses is that they easily and readily dry for long-term storage in grain bins or silos.
Haying
In animal feed production hay is dried forage (primarily grasses and forage legumes) collected and stored for fodder for grazing animals.
Salting
Sugaring
Fermentation
Pickling (acid)
Ensilage (acid)
Preservation in alcohol
Ensilage is a common form of fermentation for the preservation of silage for animal fodder, it is frequently used in areas where rainfall and humidity make it difficult to produce hay. (how to make silage) Silage is commonly kept in silos
