How to Preserve Yam for Long-Time Storage
Yams are an essential food crop in many regions of the world and are often harvested in large quantities. However, fresh yams have a relatively short shelf life, which can make it challenging to store them for long periods.
Proper storage techniques are essential to preserve the nutritional value and flavor of fresh yams. Follow the step below to preserve fresh yams for long-term storage.
Step 1: Choosing the Right Yams for Storage
The first step in preserving fresh yams is to choose the right yams for storage. When selecting yams for storage, look for ones that are firm and free of cracks, bruises, and blemishes. These are less likely to spoil during storage.

Avoid yams that have soft spots, mold, or signs of insect damage, as these can quickly deteriorate in storage.
It’s also important to choose yams that are mature but not overripe. Overripe yams are more likely to spoil quickly and have a shorter shelf life. Yams that are too young may not be fully developed and will not store well.
Step 2: Preparing Yams for Storage
Proper preparation of yams is critical to ensuring they have a long shelf life. Follow these steps to prepare yams for storage:
- Clean and wash yams thoroughly to remove any dirt, debris, or residual soil. Use a soft-bristled brush to scrub the yams gently.
- Rinse the yams in cold water to remove any remaining dirt or debris.
- Dry the yams thoroughly. Wipe them with a clean, dry towel or leave them in a well-ventilated area to air dry. Make sure the yams are completely dry before storing them.
- Treat the yams to prevent sprouting. Sprouting can occur during storage, especially if the yams are exposed to light.
To prevent sprouting, you can treat yams with a sprout inhibitor. One way to do this is by washing the yams with a solution of water and sodium bisulfate (1 tsp sodium bisulfate to 1 gallon of water).
Step 3: Methods of Long-Term Storage
There are several methods you can use to store fresh yams for an extended period. Here are some traditional and modern methods you can consider:
Method 1: Underground Pits
- Dig a hole in the ground and line it with straw, leaves, or sawdust.
- Place the yams in the pit and cover them with more straw, leaves, or sawdust.
- Cover the pit with a tarp or plastic sheet to keep out moisture and rain.
- The yams will last up to several months in the pit.
- Sand Storage
- Fill a container (e.g., wooden box or plastic container) with clean, dry sand.
- Place the yams in the sand, making sure they are completely covered.
- Store the container in a cool, dry place (e.g., basement, root cellar).
- The yams will last up to several months in the sand.
Method 2: Refrigeration
- Store the yams in a refrigerator with a temperature range of 45°F to 55°F (7°C to 13°C).
- Place the yams in a perforated plastic bag or wrap them in a paper towel to absorb any moisture.
- The yams will last up to several weeks in the refrigerator.
Method 3: Freezing
- Peel and cut the yams into small pieces.
- Blanch the yams in boiling water for 3-5 minutes.
- Cool the yams in ice water for a few minutes.
- Dry the yams and pack them in freezer-safe bags or containers.
- Store the yams in a freezer with a temperature range of 0°F to -10°F (-18°C to -23°C). The yams will last up to 12 months in the freezer.
Step 4: Monitoring and Maintaining Yams in Storage
