Sweet potato storage
Ideal storage conditions
To minimize potential spoilage, precise storage conditions should be met. Sweet potatoes should be stored at between 12 and 16 °C (54 and 61 °F) with a RH of 85-90%. Proper ventilation of the storage area is a key factor in maximizing potential storage time. Respiration causes the production of CO2, which will act to increase the rate of spoilage. Sweet potatoes can convert approximately 57dm3 of oxygen/ton/day to carbon dioxide and need ventilation to compensate for this. The O2 in the storage environment should not fall below 7% and CO2 must not exceed 10%. Due to lack of proper equipment, maintaining adequate temperature conditions are the largest hurdle that farmers in a developing nation will have to face.
