Factors affecting the storage of onions:

The major factor that determines whether the given Onion is ready to be stored or if it is going to be spoilt is its dryness. Dryness is an important factor that helps us in the storage of onions.

This is because onions lose weight during respiration. Therefore, onions are dried before storing them. The main aim of the drying process is to remove all the surface water and moisture from the onion. The Onion must be sealed by drying at least three to four layers of onion skin. As the stem is cut and it is left open it must be kept as dry as possible.

Conditions at which Onions must be stored:

First, the onions must be dried at a temperature between 25 degrees Celsius and 30 degrees celsius. Now from this level, the temperature of the Onion cold storage must be gradually decreased by 0.5 degrees Celsius per day to get to the ideal storage temperature.

The temperature is reduced until it reaches the range of zero degree Celsius to 2 degree Celsius. This gradual decrease in temperature is done for two main reasons. The first one is to make sure that the temperature of the outer layers and the bulb remains the same. The second reason is for the prevention of cells in the bulb to get destroyed.
