Sweet Potato

What to Look For

Sweet potato should be firm and smooth with no injuries to the skin or sprouting. 

Ideal Storage

  • 12.5°C - 15.5°C
  • >95% Relative Humidity for long-term storage

Store sweet potatoes in a dry and cool place. Under these conditions, sweet potatoes can be expected to keep for as long as 6-10 months, however, sprouting may occur earlier.

Sweet potato is highly sensitive to chilling injury at any temperatures below 12.5°C. Damage done to sweet potatoes may not appear until weeks or even months after the chilling injury.

Symptoms include pitting, dry matter loss and pithiness, discolouration, and increased susceptibility to decay.

Response to Ethylene

Exposure to ethylene can negatively affect the flavour of sweet potatoes.
