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.
Methods
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.
