Potato is an ideal vegetable for long-term storage due to its chemistry. Although it is still preserved in primitive warehouses and caves, it is seen that these methods are given high waste.
Seed potatoes are stored differently from other potatoes. Potatoes other than seeds are stored by undergoing a chemical process in order to prevent germination while being stored.
Storing potatoes is similar to storing onions, like all root crops, after the potato is removed from the soil, it must be dried before storage. After the drying process, To prevent rotting of potatoes injured during harvest or handling, in order to form the skin of the potato, it is treated for a while. After this time, the temperature of the potato is lowered by 0.5 degrees every day and it is prepared for cold storage. In cold stores, seed potatoes are preserved at 2-4 degrees, while other potato varieties are preserved at 4-10 degrees. However, carbon dioxide control is as important as temperature and humidity control in cold storage. Rising carbon dioxide should be controlled and kept within certain limits.
Before the potatoes are put on the market, they are prepared for distributing by increasing the temperature by 10 degrees per day without being taken out of the cold storage. Thus, condensation in the potato is prevented.
The best storage method of potatoes is modern warehouses where all stages of drying, treatment, cooling, storage and preparation for the market can be done. It is estimated that 50 million tons of 300 million tons of potatoes produced in the world are stored in this type of storage.
