How to Store Elephant Foot Yam after Harvesting?

Elephant foot yam, also known as Amorphophallus paeoniifolius, is a tropical tuber crop that is widely cultivated for its edible corms. After harvesting, proper storage techniques are crucial to maintain the quality and prevent spoilage of the yam. Here are some guidelines on how to store elephant foot yam:

1. Harvesting:

Elephant foot yam should be harvested when the leaves start turning yellow and drying up. Carefully dig out the corms from the soil using a fork or spade, ensuring minimal damage to the tubers.

2. Cleaning:

Remove the soil and any adhering debris from the harvested yam corms. Gently brush off the dirt or wash them with water if necessary. Avoid using excessive force to prevent any damage to the outer skin.

3. Drying:

Allow the yam corms to dry in a well-ventilated area for a few hours. This helps to remove excess moisture and prevents the growth of fungi or bacteria during storage.

4. Curing:

After drying, cure the yam corms by exposing them to sunlight for a few hours. This process toughens the outer skin and enhances the storage life of the yam.

5. Sorting and Grading:

Sort the yam corms based on their size and quality. Discard any damaged, diseased, or rotten tubers. Grade them into different categories for better storage management.

6. Packaging:

Place the sorted and graded yam corms in well-ventilated crates or baskets. Avoid overcrowding to allow air circulation and minimize the chances of rotting. Alternatively, you can wrap each yam in a newspaper or store them in mesh bags.

8. Regular Inspection:

Periodically check the stored yam for any signs of decay or sprouting. Remove any spoiled tubers immediately to prevent the spread of rot to other yams.

9. Shelf Life:

Under proper storage conditions, elephant foot yam can be stored for up to 3-4 months without significant loss of quality.
